Local derivations on Solvable Lie algebras [PDF]
Linear and multilinear algebra, 2018 We show that in the class of solvable Lie algebras there exist algebras which admit local derivations which are not ordinary derivation and also algebras for which every local derivation is a derivation. We found necessary and sufficient conditions under

Residually finite rationally solvable groups and virtual fibring [PDF]
, 2018 We show that a finitely generated residually finite rationally solvable (or RFRS) group $G$ is virtually fibred, in the sense that it admits a virtual surjection to $\mathbb{Z}$ with a finitely generated kernel, if and only if the first $L^2$-Betti ...

Characterizations of Fitting p-Groups whose Proper Subgroups are Solvable [PDF]
Advances in Group Theory and Applications, 2017 This work continues the study of infinitely generated groups whose proper subgroups are solvable and in whose homomorphic images normal closures of finitely generated subgroups are residually nilpotent. In [4], it has been shown that such a group, if not

One-Dimensional Quasi-Exactly Solvable Schr\"odinger Equations [PDF]
, 2016 Quasi-Exactly Solvable Schrodinger Equations occupy an intermediate place between exactly-solvable (e.g. the harmonic oscillator and Coulomb problems etc) and non-solvable ones. Mainly, they were discovered in the 1980ies.

The quest for solvable multistate Landau-Zener models [PDF]
, 2017 Recently, integrability conditions (ICs) in mutistate Landau-Zener (MLZ) theory were proposed []. They describe common properties of all known solved systems with linearly time-dependent Hamiltonians.

A second order in time, uniquely solvable, unconditionally stable numerical scheme for Cahn-Hilliard-Navier-Stokes equation [PDF]
Journal of Computational Physics, 2014 We propose a novel second order in time numerical scheme for Cahn-Hilliard-Navier-Stokes phase field model with matched density. The scheme is based on second order convex-splitting for the Cahn-Hilliard equation and pressure-projection for the Navier ...

New solvable and quasiexactly solvable periodic potentials [PDF]
Journal of Mathematical Physics, 1999 Using the formalism of supersymmetric quantum mechanics, we obtain a large number of new analytically solvable one-dimensional periodic potentials and study their properties. More specifically, the supersymmetric partners of the Lamé potentials ma(a+1)sn2(x,m) are computed for integer values a=1,2,3,… .

Schrödinger potentials solvable in terms of the general Heun functions [PDF]
, 2016 We show that there exist 35 choices for the coordinate transformation each leading to a potential for which the stationary Schrodinger equation is exactly solvable in terms of the general Heun functions.
