Exact conserved quantities on the cylinder II: off-critical case [PDF]

, 2003
With the aim of exploring a massive model corresponding to the perturbation of the conformal model [hep-th/0211094] the nonlinear integral equation for a quantum system consisting of left and right KdV equations coupled on the cylinder is derived from an

Quasiperiodic solutions for matrix nonlinear Schrödinger equations [PDF]

Journal of Mathematical Physics, 1992
The Adler–Kostant–Symes theorem yields isospectral Hamiltonian flows on the dual ■erm>$$̃g+* of a Lie subalgebra ■erm>$$̃g+ of a loop algebra ■erm>$$̃g. A general approach relating the method of integration of Krichever, Novikov, and Dubrovin to such flows is used to obtain finite-gap solutions of matrix nonlinear Schrödinger ...

Homogenized Balance Equations for Nonlinear Poroelastic Composites

Applied Sciences, 2021
Within this work, we upscale the equations that describe the pore-scale behaviour of nonlinear porous elastic composites, using the asymptotic homogenization technique in order to derive the macroscale effective governing equations. A porous hyperelastic

On (Λ,Υ,ℜ)-Contractions and Applications to Nonlinear Matrix Equations

Mathematics, 2019
In this paper, we study the behavior of Λ , Υ , ℜ -contraction mappings under the effect of comparison functions and an arbitrary binary relation. We establish related common fixed point theorems.

Linear and Riccati matrix equations

International Journal of Mathematics and Mathematical Sciences, 1989
In this paper we find exact solutions for linear ordinary differential equations of any order when they are given in matrix form, as well as for classes of Riccati matrix equations with two or three arbitrary matrix coefficients.
