I'm trying to define an anti-commutative algebra in Mathematica.
Here I will show only a minimal example to demonstrate my point.
The product of two elements a^b should be give by p[a,b] so I
make p flat:
But now I want p[a] to reduce to a.
Such a rule would make other rules much simpler but when I define
p[a_] := a
the expression p[a] causes an infinite recursion. I get the message
$IterationLimit::itlim: Iteration limit of 4096 exceeded.
I have similar problems with p:=1 which makes mathematica puts
ones into the p : p[a]=p[a,a]=p[1,1,...,a] .
How can I solve this problem?
