The Cahn–Hilliard–Hele–Shaw system with singular potential

On the singular fuzzy linear system of equations

The linear system of equations Ax = b where A = [aij ] in Cn.n is a crispsingular matrix and the right-hand side is a fuzzy vector is called a singularfuzzy linear system of equations. In this paper, solving singular fuzzy linearsystems of equations using generalized inverses such as Drazin inverse andpseudo-inverse are investigated.

Schrödinger-Maxwell equations with a singular potential

In this paper we find a ground state solution for the nonlinear Schrödinger-Maxwell equations { −∆u+ V (x)u+ φu = |u|p−1u in R3, −∆φ = u2 in R3. where V is a possibly singular potential and 3 < p < 5.

Spectral Boundary-value Problems for the Dirac System with a Singular Potential

On the Singular Spectrum of Schrödinger Operators with Decaying Potential

The relation between Hausdorff dimension of the singular spectrum of a Schrödinger operator and the decay of its potential has been extensively studied in many papers. In this work, we address similar questions from a different point of view. Our approach relies on the study of the socalled Krein systems. For Schrödinger operators, we show that some bounds on the singular spectrum, obtained rec...

Global Dynamics in the Singular Logarithmic Potential

We present an analytical description of the motion in the singular logarithmic potential of the form Φ = ln √ x1/b 2 + x2, a potential which plays an important role in the modeling of triaxial systems (like elliptical galaxies) or bars in the centers of galaxy disks. In order to obtain information about the motion near the singularity, we resort to McGehee -type transformations and regularize t...
