Query: On Koliha-Drazin invertible operators and Browder type theorems   Let $T$ be a bounded linear operator on a Banach space $X$. We give new
necessary and sufficient conditions for $T$ to be Drazin or Koliha-Drazin
invertible. All those conditions have the following form: $T$ possesses certain
decomposition property and zero is not an interior point of some part of the
spectrum of $T$. In addition, we study operators $T$ satisfying
Browder\textquoteright s theorem, or a-Browder\textquoteright s theorem, by
means of some relationships between diferent parts of the spectrum of $T$.
