We consider the problem of finding the unconstrained global minimum of a real-valued polynomial p(x): {\mathbb{R}}^n\to {\mathbb{R}}$, as well as the global minimum of p(x), in ...
Limit theorems for an $M$-estimate constrained to lie in a closed subset of $\\mathbb{R}^d$ are given under two different sets of regularity conditions. A consistent sequence of...
We analyze a minimal model of a growing network. At each time step, a new vertex is added; then, with probability delta, two vertices are chosen uniformly at random and joined b...
Operators which localise both in time and frequency are constructed. They restrict to a finite time interval and cut off low as well as high frequencies (band-pass filters). Exp...
