An Operator Method for a Third Order Partial Differential Equation equation with a
self-adjoint positive definite
operator in a Hilbert space is investigated. The main
A Glazman–Povzner–Wienholtz theorem on graphs of the underlying manifold, guarantees its essential
self-adjointness. Our aim is to extend this result
Functions of triples of noncommuting self-adjoint operators under perturbations of class Sp operators. The main result of the paper shows that unlike in the case of functions of pairs of
self-adjoint Weighted monotonicity inequalities for traces on operator algebras and B are
self-adjoint elements of the algebra in question, f and w are real-valued functions
A non-commutative version of Nikishin's theorem algebra, L1(τ) be the space of integrable
self-adjoint operators, and S be the space of
self-adjoint Weighted monotonicity inequalities for traces on operator algebras and B are
self-adjoint elements of the algebra in question, f and w are real-valued functions
On spectral problems with conditions on submanifolds of arbitrary dimensionWe consider elliptic nonnegative symmetric
operator on a closed smooth manifold on the space
