Mathematics of Computation, Vol. 87, No. 313 (September 2018), pp. 2189-2232 (44 pages) We develop a surface hopping algorithm based on frozen Gaussian approximation for semiclassical matrix ...

Pi Approximation Day 2025 is celebrated on 22 July, marking the mathematical significance of the fraction 22/7, a widely used approximation of pi. This special day honors the constant pi (π), which ...

Brilliant figures such as Sergey Nikitovich Mergelyan (1928-2008) defined the 20th century as an era for extraordinary ...

Abstract: Software implementations of mathematical functions often use approximations that can be either polynomial or rational in nature. While polynomials are the preferred approximation in most ...

Abstract: The production data of solar systems are well described by their density and distribution function. However, the mathematical description of this empirical curve is not known in closed form.
