On a characterization of polynomials among rational functions in non-archimedean dynamics

Yûsuke Okuyama, Małgorzata Stawiska

We study a question on characterizing polynomials among rational functions of degree on the projective line over an algebraically closed field that is complete with respect to…

An ADI Crank-Nicolson Orthogonal Spline Collocation Method for the Two-Dimensional Fractional Diffusion-Wave Equation

Graeme Fairweather, Xuehua Yang, Da Xu +1

A new method is formulated and analyzed for the approximate solution of a two-dimensional time-fractional diffusion-wave equation. In this method, orthogonal spline collocation is…

Best approximation on semi-algebraic sets and k-border rank approximation of symmetric tensors

Shmuel Friedland, Malgorzata Stawiska

In the first part of this paper we study a best approximation of a vector in Euclidean space R^n with respect to a closed semi-algebraic set C and a given semi-algebraic norm. Assu…

A Liouville comparison principle for solutions of semilinear parabolic second-order partial differential inequalities

Vasilii V. Kurta

We obtain a new Liouville comparison principle for entire weak solutions of semilinear parabolic second-order partial differential inequalities of the form $$ u_t -{\mathca…
