A pseudospectral mapping theorem
The pseudospectrum has become an important quantity for analyzing stability of nonnormal systems. In this paper, we prove a mapping theorem for pseudospectra, extending an earlier result of Trefethen. Our result consists of two relations that are sharp and contains the spectral mapping theorem as a special case. Necessary and sufficient conditions for these relations to collapse to an equality ...

This paper aims to present the well-known spectral mapping theorem for multi-variable functions.
متن کاملA Stochastic Contraction Mapping Theorem
The submartingale convergence theorem is often described as a stochastic analogue to the bounded convergence theorem for monotone sequences of real numbers. We define an alternative process which is a stochastic analogue to an iterative contraction process. A general convergence theorem is presented, with an extension to multivariate processes. The convergence theorem functions in a manner simi...
متن کاملThe Riemann Mapping Theorem
We will develop some of the basic concepts of complex function theory and prove a number of useful results concerning holomorphic functions. We will focus on derivatives, zeros, and sequences of holomorphic functions. This will lead to a brief discussion of the significance of biholomorphic mappings and allow us to prove the Riemann mapping theorem.
متن کاملOpen Mapping Theorem
The notation and terminology used here are introduced in the following papers: [13], [14], [3], [9], [2], [7], [1], [4], [5], [10], [6], [12], [11], and [15]. The following proposition is true (1) For all real numbers x, y such that 0 ≤ x < y there exists a real number s0 such that 0 < s0 and x < y 1+s0 < y. The scheme RecExD3 deals with a non empty set A, an element B of A, an element C of A, ...
