Penn co-authors paper in Journal of Algebra

Michael Penn

Randolph mathematics professor Michael Penn co-authored a paper that will be published in the February 2018 issue of the Journal of Algebra. The paper concludes a series of four articles—three co-authored by Penn—which examine the principal subspaces of level one standard modules of twisted affine Lie algebras using vertex algebraic techniques. Vertex algebras are a... READ MORE >>

Penn joins mathematics faculty

Michael Penn

A mathematician who specializes in abstract algebra—and pizza making—is the newest member of Randolph’s mathematics department faculty. In his first semester at Randolph this fall, math professor Michael Penn is teaching Calculus 1 and Linear Algebra and Differential Equations courses. He previously worked as a visiting professor at the University of Tennessee Chattanooga, Bowdoin College,... READ MORE >>
