On Vector-Valued Schrodinger Operators in Lp-spaces
(Universita degli studi di Salerno, 2018-04-06)
... We construct a realization Ap of A in the spaces Lp(Rd;Cm), 1 p < 1, that generates a contractive strongly continuous semigroup. First, by using form methods, we obtain generation of holomorphic semigroups when the ...
Lo pseudotensore energia-impulso in teorie estese della gravitazione
(Universita degli studi di Salerno, 2018-07-12)
The gravitational field’s energy and momentum definitions are treated in extensive gravitation theories, through the generalization of the energymomentum pseudotensor, defined by Einstein in general relativity. This ...
