On Polynomial Multiplication in Chebyshev Basis

Let $n$ and $\ell$ be positive integers and $f(x)$ be an irreducible polynomial over $\F_2$ such that $\ell deg(f(x))<2n-1.$ We obtain an effective upper bound for the multiplication complexity of $n$-term polynomials modulo $f(x)^\ell.$ This upper ...

The authors first present a class of expansions in a series of Bernoulli polyomials and then show how this general result can be applied to yield various (known or new) polynomial expansions. The corresponding expansion problem involving the Euler ...

We give an efficient multiplication method for polynomials in Chebyshev form. This multiplication method is different from the previous ones. Theoretically, we show that the number of multiplications is at least as good as Karatsuba-based algorithm. ...
