A group-theoretical classification of three-tone and four-tone harmonic chords
Jason K. C. Polak
We classify three-tone and four-tone chords based on subgroups of the symmetric group acting on chords contained within a twelve-tone scale. The actions are inversion, major-minor…
The Polypermutation Group of an Associative Ring
Jason K. C. Polak
We study permutation polynomials through the device of the \emph{polypermutation group} of an associative ring , denoted by . We derive some basic properties and c…
Counting Separable Polynomials in
Jason K. C. Polak
For a commutative ring , a polynomial is called separable if is a separable -algebra. We derive formulae for the number of separable polynomials when $R…
Exposing Relative Endoscopy in Unitary Symmetric Spaces
Jason K. C. Polák
We introduce a new class of symmetric space orbital integrals important for applications in certain relative trace formulas appearing in the theory of automorphic representations.…
