Chebyshev Varieties

Abstract

Chebyshev varieties are algebraic varieties parametrized by Chebyshev polynomials or their multivariate generalizations. They play the role of toric varieties in sparse polynomial root finding, when monomials are replaced by Chebyshev polynomials. We introduce these objects and discuss their main properties, including dimension, degree, singular locus and defining equations, as well as some computational experiments.
