Abstract:Analytic perturbations are understood here as shifts of the form
M
z
+
F
M_z + F
, where
M
z
M_z
is the unilateral shift and
F
F
is a finite rank operator on the Hardy space over the open unit disk. Here the term “a shift” refers to the multiplication operator
M

M_z
on some analytic reproducing kernel Hilbert space. In this paper, first, a natural class of… Show more
