tVeroneseIdeal -- give the Veronese ideal of t-spread monomials of a given degree

Synopsis

Description

the function tVeroneseIdeal(S,d,t) returns the Veronese ideal of t-spread monomials of degree d, that is, the ideal generated by all the t-spread monomials of S of degree dThis function calls the method tVeroneseSet(S,d,t).

Examples:

i1 : S=QQ[x_1..x_8]

o1 = S

o1 : PolynomialRing
i2 : tVeroneseIdeal(S,3,2)

o2 = ideal (x x x , x x x , x x x , x x x , x x x , x x x , x x x , x x x ,
             1 3 5   1 3 6   1 3 7   1 3 8   1 4 6   1 4 7   1 4 8   1 5 7
