Spectral analysis of differential operators with unbounded operator-valued coefficients, difference relations and semigroups of difference relations
A. G. Baskakov Voronezh State University
Abstract:
We study linear differential operators with unbounded operator-valued
coefficients acting on homogeneous spaces of functions on the semi-axis.
We obtain necessary and sufficient conditions for such operators to be
invertible or Fredholm. Essential use is made of the spectral theory
of difference relations and semigroups of linear relations
(multi-valued linear operators).
Keywords:
linear differential operators, spectrum of an operator, homogeneous spaces of functions, Green function, Fredholm operator.
