let
be an interval. a polynomial on
is a function
of the form
, where
is an integer and
are real numbers. if
, then
is called the degree of

fix a field
, and let
be variables taking values in this field. a (multilinear) monomial is a product
of variables, where
; we assume that
. the degree of this monomial is the cardinality of
. a multilinear polynomial of
variables is a function
that can be written as
for some coefficients
. the degree of
is the degree of its largest monomial:
