MATHEMATICS
On spectral properties of weighted shift operators generated by linear mappings with perron’s conditions
A. A. Ahmatova Belarusian State University, Minsk
Abstract:
Weighted shift operators $B$ in the space $L_2 (\mathbb{C}^m )$ generated by a linear mapping $A\colon\mathbb{C}^m \to \mathbb{C}^m$ are considered. A description of properties of $B - \lambda I$
for $\lambda$ belonging to spectrum $\sum(B)$ is given. In particular, the necessary and sufficient condition for $B - \lambda I$ to be one-sided invertible is obtained.
Keywords:
weighted shift operators, spectrum, one-sided invertibility, invariant measure, decomposition of oriented graph.
