Self-adjoint extensions of restrictions [PDF]
Operators and Matrices, 2008 We provide a simple recipe for obtaining all self-adjoint extensions, together with their resolvent, of the symmetric operator $S$ obtained by restricting the self-adjoint operator $A:\D(A)\subseteq\H\to\H$ to the dense, closed with respect to the graph norm, subspace $\N\subset \D(A)$. Neither the knowledge of $S^*$ nor of the deficiency spaces of $S$

Point-Like Rashba Interactions as Singular Self-Adjoint Extensions of the Schrödinger Operator in One Dimension [PDF]
Frontiers in Physics, 2019 We consider singular self-adjoint extensions for the Schrödinger operator of spin-1/2 particle in one dimension. The corresponding boundary conditions at a singular point are obtained. There are boundary conditions with the spin-flip mechanism, i.e., for

On the nonlinear perturbations of self-adjoint operators
Advances in Nonlinear Analysis, 2022 Using elements of the theory of linear operators in Hilbert spaces and monotonicity tools we obtain the existence and uniqueness results for a wide class of nonlinear problems driven by the equation Tx=N(x)Tx=N\left(x), where TT is a self-adjoint ...

Self-Adjoint Extensions of Discrete Magnetic Schrödinger Operators [PDF]
Annales Henri Poincaré, 2013 Using the concept of intrinsic metric on a locally finite weighted graph, we give sufficient conditions for the magnetic Schr dinger operator to be essentially self-adjoint. The present paper is an extension of some recent results proven in the context of graphs of bounded degree.

Jeffery-Hamel slip flow in a convergent microchannel with uniform wall temperature and streamwise heat conduction [PDF]
MATEC Web of Conferences, 2019 This work is devoted to the determination of the analytical solution of the problem of the laminar forced convection of the Jeffery-Hamel slip flow through a convergent microchannel.

Self-Adjoint Extension Approach for Singular Hamiltonians in (2 + 1) Dimensions
Frontiers in Physics, 2019 In this work, we review two methods used to approach singular Hamiltonians in (2 + 1) dimensions. Both methods are based on the self-adjoint extension approach.
