Singular Manual: determinacy

| #### D.6.19.4 determinacy Procedure from library `realclassify.lib` (see realclassify_lib). Usage: determinacy(f[, mu]); f poly, mu int Return: an upper bound for the determinacy of f Note: The characteristic of the basering must be zero, the monomial order must be local, f must be contained in maxideal(1) and the Milnor number of f must be finite. The Milnor number of f can be provided as an optional parameter in order to avoid that it is computed again. Example:
    LIB "realclassify.lib";
    ring r = 0, (x,y), ds;
    poly f = x3+xy3;
    determinacy(f);
    ==> 5
