We evaluate the matrix elements 〈r〉 for the n-dimensional harmonic oscillator in terms of the dual Hahn polynomials and derive a corresponding three-term recurrence relation and a Pasternack-type reflection relation. A short review of similar results for nonrelativistic hydrogen atom is also given. 1. An Introduction The purpose of this note is to present a simple evaluation of the expectation ...
متن کاملPhysician writers: Anton Chekhov.
Pursuing medicine means to a large extent pursuing medical science. A medical career also includes a substantial amount of writing, particularly for those who enter academia. Apart from science, during their professional lifetimes medical people are exposed to thousands of life stories, into which they, by necessity, intrude. Dealing with individual illnesses, and thus patients’ bodies, brings ...

We establish a new spectral criterion for Kazhdan's property (T) which is applicable to a large class of discrete groups defined by generators and relations. As the main application, we prove property (T) for the groups ELn(R), where n ≥ 3 and R is an arbitrary finitely generated associative ring. We also strengthen some of the results on property (T) for Kac-Moody groups from [DJ].

متن کاملGraph powers, Delsarte, . . .
The k-th p-power of a graph G is the graph on the vertex set V (G), where two k-tuples are adjacent iff the number of their coordinates which are adjacent in G is not congruent to 0 modulo p. The clique number of powers of G is poly-logarithmic in the number of vertices, thus graphs with small independence numbers in their p-powers do not contain large homogenous subsets. We provide algebraic u...
