Polynomial functions are mathematical expressions that involve variables raised to whole number powers, combined using addition, subtraction, and multiplication. They play a crucial role in ...

This function is a polynomial in two dimensions, with terms up to degree 5. It is nonlinear, and it is smooth despite being complex, which is common for computer experiment functions (Lim et al., 2002 ...

Recent research has focused on exploring the properties of polyanalytic functions, particularly in relation to Hermite polynomials, which are a class of orthogonal polynomials that arise in ...
