Aspects of multivariable operator theory on weighted symmetric Fock spaces
(World Scientific Publishing, 2014)We obtain all Dirichlet spaces Fq, q ∈ ℝ, of holomorphic functions on the unit ball of ℂN as weighted symmetric Fock spaces over ℂN. We develop the basics of operator theory on these spaces related to shift operators. We ... -
On lifting of operators to Hilbert spaces induced by positive selfadjoint operators
(Academic Press, 2005)We introduce the notion of induced Hilbert spaces for positive unbounded operators and show that the energy spaces associated to several classical boundary value problems for partial differential operators are relevant ... -
Spectra of self-similar Laplacians on the Sierpinski gasket with twists
(World Scientific Publishing Co. Pte. Ltd., 2008)We study the spectra of a two-parameter family of self-similar Laplacians on the Sierpinski gasket (SG) with twists. By this we mean that instead of the usual IFS that yields SG as its invariant set, we compose each mapping ...
