Backlund Transformations and Geometric and Complex-Analytic Background for Construction of Completely Integrable Lattice Systems
TL;DR: In this article, Backlund transformation is introduced from the point of view of isomonodromy deformation, and the axiom of permutability of BTs is equivalent to the Baxter-Zamolodchikov introduction of completely integrable quantum systems with factorized S-matrices.

Normal forms of holomorphic matrix-valued functions and corresponding forms for singular differential operators
TL;DR: In this article, the problem of holomorphic similarity of matrix-valued functions is given special consideration, and the normal forms of a holomorphic matrixvalued function under different classes of similarity transformations and corresponding forms of the singular differential operator z r d / dz − A ( z ), r ∈ N, r > 1, are investigated.

Periodic solutions of singularly-perturbed systems of differential equations with impulse effect
M. A. Hekimova,Drumi D. Bainov +1 more
TL;DR: In this article, the authors considered the problem for existence, uniqueness and asymptotic representation of periodic solutions of some singularly-perturbed systems of differential equations with impulses, with the help of a modification of the boundary functions method, adequately worked out to match the specific issues of the considered problem.
