In this article,we discuss the relationship between pointwise pseudo-orbit tracing property and chaotic properties such as topological mixing.When f has pointwi
Let Wβ(x)=exp(-1/2|x|β)be the Freud weight and pn(x) ∈пn be the sequence of orthogonal polynomials with respect to W2β(x),that is,∫∞-∞pn(x)pm(x)W2β(x)d
In this paper,we prove the dual Toeplitz algebra I(C(-Dn)) contains the ideal к of compact operators as its semicommutator ideal,and study its algebraic struct
