On norms of composition operators on weighted hardy spaces
Journal Title: JOURNAL OF ADVANCES IN MATHEMATICS - Year 2018, Vol 14, Issue 1
Abstract
The computation of composition operator on Hardy spaces is very hard. In this paper we propose a norm of a bounded composition operator on weighted Hardy spaces H2(b) induced by a disc automorphism by embedding the classical Hardy space . The estimate obtained is accurate in the sense that it provides the exact norm for particular instances of the sequence b. As an application of our results, an estimate for the norm of any bounded composition operator on H2(b) is obtained.

Bayesian estimation for the birth and death stochastic Markov chain.
In science and technology, applications of Markov chain models are varied. We consider the stochastic Markov chain by adding a stochastic term to the deterministic Markov chain. In this work, we intend the Bayesian estma...
