Conformal Laplacian And Conical Singularities, Boris Botvinnik, Serge Preston Jan 2002

Conformal Laplacian And Conical Singularities, Boris Botvinnik, Serge Preston

Mathematics and Statistics Faculty Publications and Presentations

We study a behavior of the conformal Laplacian operator $\L_g$ on a manifold with \emph{tame conical singularities}: when each singularity is given as a cone over a product of the standard spheres. We study the spectral properties of the operator $\L_g$ on such manifolds. We describe the asymptotic of a general solution of the equation $\L_g u = Q u^{\alpha}$ with 1≤αn+2 near each singular point. In particular, we derive the asymptotic of the Yamabe metric near such singularity.


Analytically Continued Hypergeometric Expression Of The Incomplete Beta Function, Jack C. Straton Jan 2002

Analytically Continued Hypergeometric Expression Of The Incomplete Beta Function, Jack C. Straton

Physics Faculty Publications and Presentations

The Incomplete Beta Function is rewritten as a Hypergeometric Function that is the analytic continuation of the conventional form, a generalization of the finite series, which simpifies the Stieltjes transform of powers of a monomial divided by powers of a binomial.


On The Evolution Of Simple Material Structures, Marek Elźanowski, Ernst Binz Jan 2002

On The Evolution Of Simple Material Structures, Marek Elźanowski, Ernst Binz

Mathematics and Statistics Faculty Publications and Presentations

The evolution of a distribution of material inhomogeneities is investigated by analyzing the evolution of the corresponding material connections. Some general geometric relations governing such evolutions are derived. These relations are then analyzed by looking at the restrictions imposed by the material symmetry group.
