Description
for univariate polynomials we have the class Polynomial
:
sage: R.<x> = QQ[] sage: isinstance(x+1, Polynomial) True
However for multivariate polynomials we have to write:
sage: R.<x,y> = QQ[] sage: isinstance(x+y, sage.rings.polynomial.multi_polynomial.MPolynomial) True
I suggest MPolynomial
is defined as an alias for
sage.rings.polynomial.multi_polynomial.MPolynomial
so that we can simply write:
sage: R.<x,y> = QQ[] sage: isinstance(x+y, MPolynomial) True

Replying to malb:
I think this needs to be discussed on [sage-devel]. Many people are pushing for less stuff in the global namespace so we cannot just add stuff without asking first.
Martin, feel free to forward to sage-devel, since I am not subscribed.
On the other hand for coherence one could replace Polynomial
by sage.rings.polynomial.polynomial_ring.Polynomial
.
