UserFunction Power


The arguments $u$ has type $DPOLID$ which abbreviates Distributive Polynomial Ideal, $n$ is a natural number.
The meaning of its parameters is as follows.

$C$: Type of coefficients.

$v=\{v_1,v_2,\ldots \}$: Distributive variables in decreasing order.

$O=LEX|GRLEX|GREVLEX$: Term order.

$n$: Nonnegative integer.

Specification. Generators for $n-$th power of ideal of $u$ are returned. In general they are not a Groebner basis.

Examples. The input is given in {\em Reduce} algebraic mode syntax. The output for each minisession
is returned in a separate window.



The given ideal:
The power ideal:
