This paper characterizes bounded, Fredholm weighted composition operators on Hardy space. As an application, the Fredholm index of such operators is obtained.
In this paper,we study some algebraic properties of Toeplitz operators with quasihomogeneous symbols on the Dirichlet space of the unit ball Bn.First,we describ
Here investigated is a kind of nonlinear combinatorial expression involving Fibonacci numbers defined on the set of integers. A number of particular consequence
Let (CΩ△) be a left triangulated category with a fully faithful endofunctor.We show a triangle-equivalence (S(C),△) ~=(S(C),△),where (S(C)△,) denotes the st
