Известия Иркутского государственного университета: Серия "Математика"A necessary and a sufficient condition for solvability of homogeneous difference equations with constant coefficients in the class of rational functions are obtained. The necessary condition is a restriction on the Newton polyhedron of the characteristic

Functions in the space R2(E) at boundary points of the interior
International Journal of Mathematics and Mathematical Sciences, 1983 Let E be a compact subset of the complex plane ℂ. We denote by R(E) the algebra consisting of (the restrictions to E of) rational functions with poles off E. Let m denote 2-dimensional Lebesgue measure.

On the Accuracy of Some Absorbing Boundary Conditions for the Schrodinger Equation
Mathematical Modelling and Analysis, 2017 A detailed analysis of absorbing boundary conditions for the linear Schrodinger equation is presented in this paper. It is focused on absorbing boundary conditions that are obtained by using rational functions to approximate the exact transparent ...

GENERALIZATIONS OF CERTAIN WELL-KNOWN INEQUALITIES FOR RATIONAL FUNCTIONS
Проблемы анализа, 2022 In this paper we generalize and refine a result of Wali and Shah concerning the estimate of the derivative of the maximum modulus of rational functions with prescribed poles and restricted zeros.

Operator-valued rational functions [PDF]
, 2022 We show that every inner divisor of the operator-valued coordinate function, zI(E), is a Blaschke-Potapov factor. We also introduce a notion of operator-valued "rational " function and then show that delta is two-sided inner and rational if and

Smoothness properties of functions in R2(x) at certain boundary points
International Journal of Mathematics and Mathematical Sciences, 1979 Let X be a compact subset of the complex plane ℂ. We denote by R0(X) the algebra consisting of the (restrictions to X of) rational functions with poles off X. Let m denote 2-dimensional Lebesgue measure. For p≥1, let Rp(X) be the closure of R0(X) in Lp(X,

Preperiodic points for rational functions defined over a rational function field of characteristic zero [PDF]
, 2015 Let k be an algebraically closed field of characteristic zero. Let K be the rational function field K=k(t). Let ϕ be a nonisotrivial rational function in K(z).
