Parabolic partial differential equations (PDEs) are fundamental in modelling a wide range of diffusion processes in physics, finance and engineering. The numerical approximation of these equations ...

Abstract: A few simple approximations are derived for erfc (x) by method of least squares (MLS). The detailed error profiles are presented. It is shown how these ...

Abstract: In this paper, we present simple approximate closed-form formulas for the average symbol error rate (SER) of M-ary phase shift keying (M-PSK) and M-ary ...

M3AS focuses on the non-trivial interplay between math, math. modelling of real sys. & math. & computer methods oriented towards the quant. & qual. anal. of real physical sys.

This peculiarity made us consider other numerical methods, seeking to identify the reasons for the behavior, either via stiffness, or by constant step methods, etc. Going beyond the usual numerical ...
