"In differential equations, the mth-degree caloric polynomial (or heat polynomial) is a "parabolically m-homogeneous" polynomial Pm(x, t) that satisfies the heat equation : \frac{\partial P}{\partial t} = \frac{\partial^2 P}{\partial x^2}. "Parabolically m-homogeneous" means : P(\lambda x, \lambda^2 t) = \lambda^m P(x,t)\text{ for }\lambda > 0.\, The polynomial is given by : P_m(x,t) = \sum_{\ell=0}^{\lfloor m/2 \rfloor} \frac{m!}{\ell!(m - 2\ell)!} x^{m - 2\ell} t^\ell. It is unique up to a factor. With t = −1, this polynomial reduces to the mth-degree Hermite polynomial in x. References *.
