Vector ** Vector -- tensor product

Synopsis

Description

If v is in the module M, and w is in the module N, then v**w is in the module M**N.
i1 : R = ZZ[a..d];
i2 : F = R^3

o2 = R

o2 : R-module, free
i3 : G = coker vars R

o3 = cokernel | a b c d |

                            1
o3 : R-module, quotient of R
i4 : v = (a-37)*F_1
