Computing Fourier transforms and convolutions of Sn-1-invariant signals on Sn in time linear in n
Let Sn denote the symmetric group on {1, . . . , n} and Sn-1 the stabilizer subgroup of n. We derive algorithms for computing Fourier transforms of left and right Sn-1-invariant s...

Formal Series of General Algebras over a Field and Their Syntactic Algebras
Any mapping S : C → K, where K is a field and C = (C, Σ) is a Σ-algebra, is called a KC-series. These series are natural generalizations of both formal series on strings over...
