Boundary value problems for matrix Euler-Poisson-Darboux equation with data on a characteristic
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015 We consider the system of $n$ partial differential equations in matrix notation (the system of Euler-Poisson-Darboux equations). For the system we formulate the Cauchy-Goursat and Darboux problems for the case when the eigenvalues of the coefficient ...

Guaranteed Minimum-Rank Solutions of Linear Matrix Equations via Nuclear Norm Minimization [PDF]
SIAM Review, 2007 The affine rank minimization problem consists of finding a matrix of minimum rank that satisfies a given system of linear equality constraints. Such problems have appeared in the literature of a diverse set of fields including system identification and ...

Solving ill-conditioned linear equations using simulated annealing method [PDF]
Journal of Hyperstructures, 2018 The purpose of this paper is to using the Simulated Annealing method to solving a linear equations system which have an ill-conditioned coefficients matrix. A linear equation system is called ill-conditioned if its condition number be large.

A New Analytic Solution Method for a Class of Generalized Riccati Differential Equations
Universal Journal of Mathematics and Applications, 2023 We give a useful and practicable solution method for the general Riccati differential equation of the form $w^{\prime }\left( x\right) =p\left( x\right) +q\left( x\right) w\left( x\right) +r\left( x\right) w^{2}\left( x\right) $.
