✦ Synopsis

We prove a structure theorem for conic involutive varieties of the cotangent bundle of a smooth algebraic variety X whose projection on X is smooth. The paper includes an example of a conic involutive variety of T ଙ X which is not the characteristic variety of any D D -module.

In this paper we construct families of compactly supported nonseparable interpolating refinable functions with arbitrary smoothness (or regularity). The symbols for the newly constructed scaling functions are given by a simple formula related to the Bernstein polynomials. The emphasis of the paper i

In this note we describe aspects of the cohomology of coherent sheaves on a complete toric variety X over a field k and, more generally, the local cohomology, with supports in a monomial ideal, of a finitely generated module over a polynomial ring S. This leads to an efficient way of computing such
