# Ring _ List -- make a monomial from a list of exponents

## Synopsis

• Operator: _
• Usage:
R_w
• Inputs:
• Outputs:
• , the monomial of the ring R obtained by using the integers in the list w as exponents of the variables.

## Description

 i1 : R = ZZ[a..d] o1 = R o1 : PolynomialRing i2 : R_{3,1,5} 3 5 o2 = a b*c o2 : R i3 : R_{1,1,1,1} o3 = a*b*c*d o3 : R i4 : S = R[x,y,z] o4 = S o4 : PolynomialRing i5 : S_{1,1,1} o5 = x*y*z o5 : S i6 : S_{1,1,1,4} 4 o6 = a x*y*z o6 : S
