Introduction

AVF is a Mathematica package for

There are specific programs for generation and use of Clifford algebra valued forms with moving frames, and generalizations.

The AVF package is essentially independent of the rest of the xAct packages. It is included in the xAct framework because it covers a complementary area. It does not yet talk to the other mathematical packages as it uses a different, mostly index-free, approach.

Jose: This package is a small modification of a suite of programs written by Hugo D. Wahlquist in 2003, used and tested by him and his collaborator Frank B. Estabrook. The original programs, as written by Hugo D. Wahlquist, can be obtained from http://www.emis.de/journals/SIGMA/2008/063/. Hugo passed away in 2008, and Frank has kindly authorized AVF is included in the xAct suite.
