OPEIntegrateDelta[expr, x, m]
introduces the (DeltaFunction[1-x]
).
The Mathematica Integrate
function is called and each integration (from to ) is recorded for reference (and bug-checking) in the list $MIntegrate
.
Notice that the dimension specified by the option should also be the dimension used in expr
. It is replaced in OPEIntegrateDelta by (4+Epsilon
).
