Abstract: AbstractThis paper deals with both integrability and linearizability problems of three dimensional Lotka–Volterra systems at the origin with rank-2. We give necessary conditions of a system with quadratic nonlinearities with $$(1:3:-\,1)$$(1:3:-1)-resonance. We proved the sufficiency… read more here.

DOI: 10.3103/s1066369x20060031
Abstract: We apply new approach for the Goursat and Cauchy problems with additional recovering of coefficients of equation for selection of the cases of solvability of these problems in quadratures. Instead of introduction of additional boundary… read more here.
