The Pfeiffer-Lax-Sato type vector field equations and the related integrable versal deformations
We study versal deformatiions of the Pfeiffer-Lax-Sato type vector field equations, related with a centrally extended metrized Lie algebra as the direct sum of vector fields and differential forms on torus.
Review of the book by Mariusz Urbanek, “Genialni – Lwowska Szko la Matematyczna"( Polish) [Geniuses – the Lvov school of mathematics], Wydawnictwo Iskry, Warsaw 2014, 283 pp. ISBN: 978-83-244-0381-3
This review is an extended version of my short review of Urbanek's book that was published in MathSciNet. Here it is written about his book in greater detail, which was not possible in the short review. I will present fa...

On uniqueness of entropy solutions for nonlinear elliptic degenerate anisotropic equations
In the present paper we deal with the Dirichlet problem for a class of degenerate anisotropic elliptic second-order equations with L1-right-hand sides in a bounded domain of Rn (n⩾2). This class is described by the prese...
On the transcendental meromorphic solutions of a certain class of differential equations
In this paper we consider the differential equation F(k)−a2=eγ{α(F−a1)+β}, where ai(z),α(z)(≢0,∞), β(z)(≢∞), i=1,2 are small functions of F, γ is an entire function and k∈N. Let f be a transcendental meromorphic functi...
