LPP -- the leading power-product of a polynomial or ModuleElem |
Syntax |
LPP(X: RINGELEM): RINGELEM LPP(X: MODULEELEM): RINGELEM |
Description |
Example |
/**/ use R ::= QQ[x,y]; /**/ LPP(3*x^2*y+y); -- LPP is the same as LT for polynomials x^2*y -- Note the difference between LPP and LT for MODULEELEM. /**/ R4 := NewFreeModule(R,4); -- the default module ordering is TOPos /**/ LPP(ModuleElem(R4, [0, x, y^2, x^2])); x^2 /**/ LT(ModuleElem(R4, [0, x, y^2, x^2])); [0, 0, 0, x^2] /**/ LPosn(ModuleElem(R4, [0, x, y^2, x^2])); 4 |
