In this note we address the question whether for a given prime number p, the zeta-function of a number field always determines the p-part of its class number. The answer is known t...
Abstract. In this note we study the local behavior of singularities occurring in scale space under Gaussian blurring. Based on ideas from singularity theory for vector fields this...
We study the complexity of testing if two given matroids are isomorphic. The problem is easily seen to be in Σ p 2. In the case of linear matroids, which are represented over pol...
Two difficulties connected with the solution of Laplace's equation around an object inside an infinite circular cylinder are resolved. One difficulty is the nonconvergence of...
In theoretical cryptography, one formalizes the notion of an adversary's success probability being "too small to matter" by asking that it be a negligible function ...
