D.5.5.20 computemcm
Procedure from library resbinomial.lib (see resbinomial_lib).
- Usage:
- computemcm(Eolist); Eolist list
- Return:
- an integer, the least common multiple of the denominators of the E-orders
- Note:
- Make the same as lcmofall but for one chart. NECESSARY BECAUSE THE E-ORDERS ARE OF TYPE NUMBER!!
Example:
| | LIB "resbinomial.lib";
ring r = 0,(x(1..2)),dp;
ideal J=x(1)^3-x(1)*x(2)^3;
list L=Eresol(J); // 8 charts, rational exponents
L[8][2][2]; // maximal E-order at the first chart
==> [1]:
==> 3
==> [2]:
==> 9/2
computemcm(L[8][2][2]);
==> 2
