Abstract: Hodge theory provides a unifying view of the various line, surface, and volume integrals that appear in physics and engineering applications. Hodge theory on graphs develops discrete ...

Gain a clear understanding of line integrals through the vector field 𝐹 = 𝑋 𝑖 ^ × 𝑌 𝑖 ^ − 𝑌 𝑖 ^ F=X i ^ ×Y i ^ −Y i ^ in this detailed physics and math tutorial. This video breaks down the ...

Abstract: This paper aims to provide a tutorial on Bessel functions, and especially on the numer cal evaluation of Bessel integrals. Bessel integrals are asymptotically evaluated using high-frequency ...

FDINT is a free, open-source python package that provides fast, double precision (64-bit floating point) approximations to the Fermi-Dirac integrals of integer and half integer order, based on the ...
