Synopsis
Usage:
CSMClassList I
CSMClassList X
Inputs:

, a homogeneous ideal in a polynomial ring over a field, defining a projective scheme X
X
,
a
projective variety
Optional inputs
:
ResidualStrategy =>
Symbolic
,
default value Symbolic

(T
X
),..., deg (c
SM
)
n
(T
X
) }, of the degrees of the Chern-Schwartz-MacPherson classes of X
Description
This function does the same as the function
CSMClass
, but provides an output that is easier to read for a computer.
