Description

I propose adding a LaurentPolynomial ring extension.

History

#1 Updated by John Abbott about 9 years ago

There are two cases to consider:
  • dense univariate
  • sparse multivariate

One "easy" solution is to use existing data structures together with a "shift" to be added to the exponents.

While the user could employ explicitly this trick above for representing laurent polys, it would be nicer to offer a built-in way of expressing them (so that the user does not need to resort to "tricks").
