Heat polynomial analogues for equations with higher order time derivatives

Abstract: We generalize the heat polynomials for the heat equation to more general partial differential equations, of higher order with respect to both the time variable and the space variables. Whereas the heat equation requires only one family of polynomials, for an equation of the th order with respect to time we introduce families of polynomials. These families correspond to the initial conditions specified by the Cauchy problem.

“…Among these classical polynomials are the heat polynomials (also designated as Temperature polynomials) that are polynomial solutions of the heat equation and also are particularly useful in solving the Cauchy problem (see [23][24][25][26]). Special functions, such as the confluent hypergeometric function, integral error functions, and Laguerre polynomials, have a close link with the generalized heat polynomials intro-duced [27][28][29].…”

“…Many works of scientists [14][15][16] are devoted to constructing the polynomial and quasi-polynomial solutions for the equations and boundary-value problems for them. Let us note that function (4), which is a nontrivial solution to the homogeneous problem (1), (3) is quasi-polynomial, which can be written in the form U(t, x) = Ae αt (e βx + e −βx ) − Ae −αt (e βx + e −βx ),…”
