Partial Difference Sets In P-Groups, James A. Davis
Partial Difference Sets In P-Groups, James A. Davis
Department of Math & Statistics Faculty Publications
Most of the examples of PDS have come in p-groups, and most of these examples are in elementary abelian p-groups. In this paper, we will show an exponent bound for PDS with the same parameters as the elementary abelian case.
Bergman Spaces On An Annulus And The Backward Bergman Shift, William T. Ross
Bergman Spaces On An Annulus And The Backward Bergman Shift, William T. Ross
Department of Math & Statistics Technical Report Series
In this paper, we will give a complete characterization of the invariant subspaces M (under ƒ → zƒ) of the Bergman space Lpa(G), 1 < p < 2, G an annulus, which contain the constant function 1. As an application of this result, we will characterize the invariant subspaces of the adjoint of multiplication by z on the Dirichlet spaces Dq, q > 2, as well as the invariant subspaces of the backward Bergman shift ƒ → (ƒ – ƒ(0))/z on Lpa(𝔻), 1 < p < 2.
A Construction Of Difference Sets In High Exponent 2-Groups Using Representation Theory, James A. Davis, Ken Smith
A Construction Of Difference Sets In High Exponent 2-Groups Using Representation Theory, James A. Davis, Ken Smith
Department of Math & Statistics Faculty Publications
Nontrivial difference sets in groups of order a power of 2 are part of the family of difference sets called Menon difference sets (or Hadamard), and they have parameters (22d+2, 22d+1 ±2d, 22d±2d). In the abelian case, the group has a difference set if and only if the exponent of the group is less than or equal to 2d+2. In [14], the authors construct a difference set in a nonabelian group of order 64 and exponent 32. This paper generalizes that result to …
Analytic Besov Spaces And Invariant Subspaces Of Bergman Spaces, William T. Ross
Analytic Besov Spaces And Invariant Subspaces Of Bergman Spaces, William T. Ross
Department of Math & Statistics Faculty Publications
In this paper, we examine the invariant subspaces (under the operator f -->z f) M of the Bergman space pa (G\T) (where 1 < p < 2, G is a bounded region in C containing D, T is the unit circle, and D is the unit disk) which contain the characteristic functions xD and xG, i.e. the constant functions on the components of G\T. We will show that such M are in one-to-one correspondence with the invariant subspaces of the analytic Besov space ABq (q is the conjugate index to p) and …
Invariant Subspaces Of Bergman Spaces On Slit Domains, William T. Ross
Invariant Subspaces Of Bergman Spaces On Slit Domains, William T. Ross
Department of Math & Statistics Faculty Publications
In this paper, we characterize the z-invariant subspaces that lie between the Bergman spaces Ap(G) and Ap(G\K), where 1 < p < ∞, G is a bounded region in C, and K is a closed subset of a simple, compact, C1 arc.

An Invariant Subspace Problem For P = 1 Bergman Spaces On Slit Domains, William T. Ross
An Invariant Subspace Problem For P = 1 Bergman Spaces On Slit Domains, William T. Ross
Department of Math & Statistics Faculty Publications
In this paper, we characterize the z-invariant subspaces that lie between the Bergman spaces A1(G) and A1(G/K), where G is a bounded region in the complex plane and K is a compact subset of a simple arc of class C1.
