Polynomial and special function theory remains a vibrant area of mathematical research, interweaving classical algebra with advanced analysis. At its core, the study concerns algebraic expressions ...

The conditional variance function in a heteroscedastic, nonparametric regression model is estimated by linear smoothing of squared residuals. Attention is focused on local polynomial smoothers. Both ...

The present paper deals with an application of Jacobi polynomial and multivariable H-function to solve the differential equation of heat conduction in a non-homogeneous moving rectangular ...
