Free integro-differential algebras and Groebner-Shirshov bases [PDF]

, 2014
The notion of commutative integro-differential algebra was introduced for the algebraic study of boundary problems for linear ordinary differential equations. Its noncommutative analog achieves a similar purpose for linear systems of such equations.

First Integrals and Exact Solutions of a System of Ordinary Differential Equations with Power Nonlinearity

Известия Иркутского государственного университета: Серия "Математика", 2017
The system of ordinary differential equations with degree nonlinearities is considered. Systems of such kind arise as comparison systems at stability analysis by means non-linear approximation and at application of reduction method to switched systems ...

R-deformed Heisenberg algebra, anyons and d=2+1 supersymmetry [PDF]

, 1997
A universal minimal spinor set of linear differential equations describing anyons and ordinary integer and half-integer spin fields is constructed with the help of deformed Heisenberg algebra with reflection. The construction is generalized to some d=2+1
