The Positive Supercyclicity Theorem.
We present some recent results related with supercyclic operators, also some of its consequences. We will finalize with new related questions.
Positivity in the theory of supercyclic operators
A bounded linear operator T defined on a Banach space X is said to be supercyclic if there exists a vector x ∈ X such that the projective orbit {λTⁿx : λ ∈ ℂ, n ∈ ℕ} is dense in X. The aim of this survey is to show the relationship between positivity and supercyclicity. This relationship comes from the so called Positive Supercyclicity Theorem. Throughout this exposition, interesting new directions and open problems will appear.
