`desing/findt2`

Computation of the Gamma function defined in section 5 page 165-166 in [EV00]. In this case the list of exceptional divisors are not specified by indices to the IND entry of the chart, but they are given by equations; therefore an arbitrary pair need not have a common point.

Input:

 

a

the list of weights of the exceptional divisors,

E

the list of defining equations of the exceptional divisors,

S

the list of variables of the chart

DEP

the list of algebraic dependencies of S.

Output:

A list of indices to E that are chosen by the Gamma function.
