Factorization of a class of Toeplitz + hankel operators and the A_p-condition

Estelle L. Basor, Torsten Ehrhardt

Let $M(\varphi )=T(\varphi )+H(\varphi )$ be the Toeplitz plus Hankel operator acting on $H^p(\T)$ with generating function $ϕ\in L^\iy(\T)$. In a previous paper we proved that $M(\varphi )$ is invertible if…
