Degree for constant

Defining `degree` on constants would be useful so that when you substitute the last variable it still works. cc @SergioCS147

https://github.com/JuliaSymbolics/SymbolicUtils.jl relies on `gcd` to simplify fractions. This is currently the performance bottleneck and while the current implementation was focused on correctness, we should now perform a detailed performance benchmark...

Cannot create zero polynomial

2

I have a very surprising problem, it is impossible to create a Multivariate Polynomial that is constantly zero. This code crashes on my computer: ```julia using MultivariatePolynomials using TypedPolynomials @polyvar...

added type for differentiate in chain_rules.jl

1

1. We should make sure that differentiate is being called on a polynomial p. (It is possible there are other meanings of differentiate for other types in the code.) 2....

Complex polynomials

2

I would like to discuss your thoughts and possibilities to add more support for complex-valued variables to the polynomials. This was already partially mentioned in #11 (conjugation). In #116, it...

Fix rrule for * and add support for constant operations

2

I am a bit unsure what to do here. I think we should define `rrule` based on `LinearAlgebra.dot` so we should remove the definition of the rule for `differentiate` and...
