D.6.12.2 KSconvert

Procedure from library kskernel.lib (see kskernel_lib).

Usage:
KSconvert(matrix M);
M is a matrix of coefficients of the generators of
the kernel of Kodaira-Spencer map in variables T(i)
from the basering. To be called after the procedure
KSker(p,q)

Return:
nothing; exports ring KSring2 and matrix KSkernel2 within it, such that KSring2 resp. KSkernel2 are in variables
T(w) with weights -w. These weights are computed
in the procedure KSker(p,q)

Example:
 
LIB "kskernel.lib";
int p=6;
int q=7;
KSker(p,q);
setring Kskernel::KSring;
KSconvert(KSkernel);
==> // ** `KSring2` is already global
setring Kskernel::KSring2;
print(KSkernel2);
==> 0,     0,     0,             0,             0,             2*T(2),  
==> 0,     0,     0,             0,             0,             3*T(3),  
==> 0,     0,     0,             0,             0,             4*T(4),  
==> 0,     0,     0,             2*T(2),        3*T(3),        9*T(9),  
==> 0,     0,     0,             3*T(3),        KSkernel2[5,5],10*T(10),
==> 2*T(2),3*T(3),KSkernel2[6,3],KSkernel2[6,4],KSkernel2[6,5],16*T(16)
