We present the tensor computer algebra package xTras, which provides functions and
methods frequently needed when doing (classical) field theory. Amongst others, it can …

The complicated nature of calculations in general relativity was one of the driving forces in
the early development of computer algebra (CA). CA has become widely used in gravity …

Field theory is an area in physics with a deceptively compact notation. Although general
purpose computer algebra systems, built around generic list-based data structures, can be …

Package'FeynGrav'which provides a framework to operate with Feynman rules for gravity
within'FeynCalc'is presented. We present a framework to deal with Feynman rules for …

We present a new version of FeynGrav. The present version supports Feynman rules for
matter with non-vanishing mass and SU (N) Yang-Mills model. We revisit the gauge fixing …

Superfield methods can be used to determine the precise way the self-dual five-form
couples to the metric in the first non-trivial α'corrections to type IIB supergravity. We explicitly …

Field theory is an area in physics with a deceptively compact notation. Although general
purpose computer algebra systems, built around generic list-based data structures, can be …

The motion of water is governed by the Navier–Stokes equations, which are complemented
by the continuity equation to ensure local mass conservation. In this work, we construct the …

There are various types of global and local spacetime invariant in general relativity. Here I
focus on the local invariants obtainable from the curvature tensor and its derivatives. The …

Abstract The book “Handbook of Finsler geometry” has been included with a CD containing
an elegant Maple package, FINSLER, for calculations in Finsler geometry. Using this …
