Singular Manual: abstractR

| #### D.5.16.7 abstractR Procedure from library `reszeta.lib` (see reszeta_lib). Usage: abstractR(L); L = list of rings Assume: L is output of resolution of singularities Note: currently only implemented for isolated surface singularities Return: list l l[1]: intvec, where l[1][i]=1 if the corresponding ring is a final chart of non-embedded resolution l[1][i]=0 otherwise l[2]: intvec, where l[2][i]=1 if the corresponding ring does not occur in the non-embedded resolution l[2][i]=0 otherwise l[3]: list L Example:
    LIB "reszeta.lib";
    ring r = 0,(x,y,z),dp;
    ideal I=x2+y2+z11;
    list L=resolve(I);
    list absR=abstractR(L);
    absR[1];
    ==> 0,0,1,1,0,1,0,1,0,1,1,0,0,0,0,0,0
    absR[2];
    ==> 0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1
