Rocky Mountain Journal of Mathematics publishes both research and expository articles in mathematics, and particularly invites well-written survey articles. The Rocky Mountain Journal of Mathematics ...

Get ready to use the BigInteger data type as Dr. James McCaffrey of Microsoft Research demonstrates zero-based mathematical permutations with C#. A zero-based mathematical permutation of order n is a ...

Let $G$ be a finite group with center $Z. G$ acts on itself by conjugation, and this induces a permutation representation $P$ of $G/Z$. It has been conjectured that ...

A new proof from the Australian science fiction writer Greg Egan and a 2011 proof anonymously posted online are now being hailed as significant advances on a puzzle mathematicians have been studying ...

Quantum spin systems occupy a central role in understanding magnetic phenomena and phase transitions at the microscopic level. In these systems, intrinsic angular momentum (spin) interactions give ...

Representation theory was initially dismissed. Today, it’s central to much of mathematics. When representation theory emerged in the late 19th century, many mathematicians questioned its worth. In ...
