This chapter describes interface functions for
sm1 ox server ox_sm1_forAsir
.
These interface functions are defined in the file `sm1'.
The file `sm1' is
at `$(OpenXM_HOME)/lib/asir/contrib-packages'.
The system sm1
is a system to compute in the ring of differential
operators.
Many constructions of invariants
in the computational algebraic geometry reduce
to constructions in the ring of differential operators.
Documents on sm1
are in
the directory OpenXM/doc/kan96xx
.
All the coefficients of input polynomials should be integers for most functions in this section. Other functions accept rational numbers as inputs and it will be explicitely noted in each explanation of these functions.
