Characterization of Oblique Dual Frame Pairs

open access: yesEURASIP Journal on Advances in Signal Processing, 2006
Given a frame for a subspace of a Hilbert space , we consider all possible families of oblique dual frame vectors on an appropriately chosen subspace .

Finding metastabilities in reversible Markov chains based on incomplete sampling

open access: yesSpecial Matrices, 2017
In order to fully characterize the state-transition behaviour of finite Markov chains one needs to provide the corresponding transition matrix P. In many applications such as molecular simulation and drug design, the entries of the transition matrix P ...

Invariant Means and Reversible Semigroup of Relatively Nonexpansive Mappings in Banach Spaces

open access: yesAbstract and Applied Analysis, 2014
The purpose of this paper is to study modified Halpern type and Ishikawa type iteration for a semigroup of relatively nonexpansive mappings I={T(s):s∈S} on a nonempty closed convex subset C of a Banach space with respect to a sequence of asymptotically ...
