Overview
A
bstract
We give an explanation of the d log-form of the coefficient matrix of canonical differential equations using the projection of (
n
+1)-d log forms onto
n
-d log forms. This projection is done using the leading-order formula for intersection numbers. This formula gives a simple way to compute the coefficient matrix. When combined with the relative twisted cohomology, redundancy in computation using the regulator method can be avoided.
