Global Convergence For Discrete Dynamical Systems And Forward Neural Networks, Asuman G. Aksoy, Mario Martelli Jan 2001

Global Convergence For Discrete Dynamical Systems And Forward Neural Networks, Asuman G. Aksoy, Mario Martelli

Turkish Journal of Mathematics

Using a theoretical result regarding the global stability of discrete dynamical systems of lower triangular form, we establish convergence properties of forward neural networks when the neuron response functions fail to be continuous.


On Qr-Submanifolds Of A Quaternionic Space Form, Bayram Şahi̇n Jan 2001

On Qr-Submanifolds Of A Quaternionic Space Form, Bayram Şahi̇n

Turkish Journal of Mathematics

In this paper, we investigate mixed QR-submanifolds in a quaternionic space form and pseudo umbilical QR-submanifold of a quaternionic space form under some additional condition. Finally we give a necessary condition for QR-submanifold of a quaternion Kaehler manifold such that \dim \upsilon ^{\perp }=1 to be a 3-quasi Sasakian Manifold.


Torus Fibrations On Symplectic Four-Manifolds, Ivan Smith Jan 2001

Torus Fibrations On Symplectic Four-Manifolds, Ivan Smith

Turkish Journal of Mathematics

This paper has two essentially unrelated halves. In the first we prove that a closed symplectic four-manifold admitting a fibration by connected, homologically essential Lagrangian tori with "tame" singularities, is fibre-preserving diffeomorphic to a K3 surface or to a torus bundle over a torus with first Betti number at least three. In the second, we prove that these torus bundles over tori admit Lefschetz pencils by genus three curves. It follows that the genus three mapping class group admits infinitely many inequivalent irreducible positive relations. Motivations for the questions are provided from mirror symmetry, integrable systems and Seiberg-Witten theory: in …


A Partial Order On The Group Of Contactomorphisms Of $\R^{2n+1}$ Via Generating Functions, Mohan Bhupal Jan 2001

A Partial Order On The Group Of Contactomorphisms Of $\R^{2n+1}$ Via Generating Functions, Mohan Bhupal

Turkish Journal of Mathematics

In this note we construct a nontrivial partial order on the identity component of the group of compactly supported contactomorphisms of \R^{2n+1} using the method of generating functions. Our construction is in the framework of the theory developed by Viterbo in the paper \cite{V} wherein, among other things, he showed how one could use generating functions to construct a partial order on the group of compactly supported Hamiltonian symplectomorphisms of \R^{2n}.


Knotting Of Algebraic Curves In Complex Surfaces, Sergey Finashin Jan 2001

Knotting Of Algebraic Curves In Complex Surfaces, Sergey Finashin

Turkish Journal of Mathematics

For any d\ge 5, I constructed infinitely many pairwise smoothly non-equivalent surfaces F\subset\Cp{2} homeomorphic to a non-singular algebraic curve of degree d, realizing the same homology class as such a curve and having abelian fundamental group \pi_1(\Cp2\stmin F). It is a special case of a more general theorem, which concerns for instance those algebraic curves, A, in a simply connected algebraic surface, X, which admit irreducible degenerations to a curve A_0, with a unique singularity of the type X_9, and such that A\cite A>16.


The Verlinde Algebra Is Twisted Equivariant K-Theory, Daniel S. Freed Jan 2001

The Verlinde Algebra Is Twisted Equivariant K-Theory, Daniel S. Freed

Turkish Journal of Mathematics

The Verlinde algebra, which mathematically appears in the theory of loop groups and is related to moduli spaces of bundles over curves, turns out to be describable in terms of K-theory. This is a joint discovery with M. Hopkins and C. Teleman. Here we explain in heuristic terms how this fits naturally into ideas about the Chern-Simons topological field theory.


Induced Cat^1-Groups, Murat Alp Jan 2001

Induced Cat^1-Groups, Murat Alp

Turkish Journal of Mathematics

In this paper we define the pullback cat^1-group and show that this Pullback has a right adjoint which is the induced cat^1-group. Later we show that this right adjoint is a pushout of category of cat^1-groups. We calculate the Peiffer subgroups to find a finite group of the source of induced cat^1-groups. The generating set of Peiffer subgroups are also given in this paper. All results are corrected by a GAP[13] program package in [4]. This paper also contains the some computational examples which are the calculation-induced cat^1-group and comparative times between the induced crossed modules and induced cat^1-groups.


P -Banach Algebras With Generalized Involution And C^*-Algebra Structure, Abdellah El Kinani, Aziz Ifzarne, Mohamed Oudadess Jan 2001

P -Banach Algebras With Generalized Involution And C^*-Algebra Structure, Abdellah El Kinani, Aziz Ifzarne, Mohamed Oudadess

Turkish Journal of Mathematics

In this paper, we consider p-Banach algebras endowed with a generalized involution. We show that various C^*-like conditions force the algebra to be C^*-algebra under an equivalent norm.

The Impact Of Financial Reform On Private Savings In Bangladesh, Abdur Chowdhury Jan 2001

The Impact Of Financial Reform On Private Savings In Bangladesh, Abdur Chowdhury

Economics Faculty Research and Publications

Over the course of the last decade, Bangladesh has implemented a broad-based program of financial and market reforms, encompassing changes in the structure of the financial system, prudential and supervisory frameworks, and monetary management. This paper estimates a savings function to evaluate the impact of various determinants of private savings in Bangladesh—with special emphasis on the impact of financial reform. The results show that the level of income, real interest rates, and the share of agriculture in GDP have a positive impact on the savings rate. Dependency rate and public savings rate, on the other hand, have a negative impact …


External Debt And Growth In Developing Countries: A Sensitivity And Causal Analysis, Abdur Chowdhury Jan 2001

External Debt And Growth In Developing Countries: A Sensitivity And Causal Analysis, Abdur Chowdhury

Economics Faculty Research and Publications

The paper aims to enhance the existing literature on the debt-growth nexus by analysing the relationship in two separate country groups using the extreme bounds analysis for sensitivity tests and the mixed, fixed, and random coefficient approach that allows for heterogeneity in the causal relationship between debt and growth. Irrespective of the debt measure used, the results are robust across the two country groups—HIPC and non-HIPC—as well as two different testing procedures. The extreme bounds analysis shows that the relationship between a debt measure and economic growth is robust to changes in the conditioning set of information included in the …


On The L^P Solutions Of Dilation Equations, İbrahi̇m Kirat Jan 2001

On The L^P Solutions Of Dilation Equations, İbrahi̇m Kirat

Turkish Journal of Mathematics

In this paper, the concepts concerning the space of constant breadth were extended to E^n-space. An approximate solution of the equation system which belongs to this curve was obtained. Using this solution vectorial expression of the curves of constant breadth was obtained. The relation \int_0^{2\pi}\widetilde{f}(s)\,ds=0 between the curvatures of curves of constant breadth in E^n was obtained.

The aim of this paper is to introduce the class of OFR-sets as the sets that are the intersection of an open set and a feeble-regular set. Several classes of matroids are studied via the new concept. New decompositions of strong maps are provided.

Investment Performance Comparison Between Roth And Traditional Individual Retirement Accounts, George Kutner, Lloyd Doney, James Trebby Jan 2001

Investment Performance Comparison Between Roth And Traditional Individual Retirement Accounts, George Kutner, Lloyd Doney, James Trebby

Accounting Faculty Research and Publications

With the recent introduction of the Roth Individual Retirement Account (IRA) along with a significantly improved Traditional IRA, there has been considerable interest in comparing the performance of these investment vehicles. Some confusion regarding these comparisons has evolved. In this paper we show that this confusion may be attributed to scale and tax differences between the two investment vehicles. We adjust for these differences by focusing on the after-tax rate-of-return on investment for each IRA vehicle. We find that performance depends crucially on the relationship between an individual's tax rates at the time of investment and at the time of …
