Hi Sagen, Has anyone implemented a non-trivial Clifford algebra module? Such a thing would be able to generate higher algebras recursively and exhibit 8-fold periodicity, as well as being useful for actual calculation. thanks (on 8.4 as of today) -drl -- You received this message because

I attempted to create a Clifford Algebra for space-time with the gamma matrices using the FreeAlgebraQuotient in analogy to the example for constructing a quarternion algebra from the documentation with the code: PRGA=FreeAlgebra(QQ,4,'g') F = PRGA.monoid() g0,g1,g2,g3 = F.gens() mons = [ F(1),

Have you looked at what sympy already has for Clifford algebras? On Saturday, July 26, 2014, Stephen Kauffman strangerl...@gmail.com wrote: I attempted to create a Clifford Algebra for space-time with the gamma matrices using the FreeAlgebraQuotient in analogy to the example for constructing

plenty to read in http://docs.sympy.org/latest/modules/galgebra/GA.html had to dig to see what to import import sympy from sympy import * from sympy.galgebra import * from sympy.galgebra.ga import * some references said to from sympy.galgebra.GAsympy import * which doesn't exist or at least

Hi, I am currently trying to switch from commercial CAS to sage. As a physicist I need to handle non-commutative algebras, most notably Clifford algebras. I have read that GiNaC is pretty good in that and that sage is using a variant called Pynac. Does Pynac have the non-commutative
