This paper
was inspired by my one-week residency at an AIM-NSF workshop called
"Research Experiences for Undergraduate Faculty" at ICERM in
Providence, RI, in June 2012. It contains
some of our
unpublished results, and also includes exercises and project ideas that
faculty can use to involve undergraduates in
research in the areas of Combinatorics, Graph Theory, and Number
Theory (2012). (Available by clicking here).

- On a coin-flip problem and its connection to pi. I wrote this with the intention of using it as a teaching (learning) tool for other faculty (students). Hence many exercises are included (2011). (Available by clicking here).

Here are brief introductions to some selected objects and ideas that I think about:

- On my Schur-Weyl duality project. This 2 page write-up describes the problem that I am working on. It is also a good introduction for an undergraduate interested in doing research with me on this project.
- Complex reflection groups. This 5 page write-up briefly describes the family of imprimitive complex reflection groups (giving various combinatorial ways of viewing their elements), irreducible representations of these groups, a description (and an example) of a generalized Robinson-Schensted correspondence between these groups and pairs of same-shape multitableaux, and some combinatorial implications of the latter map.

PROCLAIMER: Click on "Proclaimer", and Tibetan Buddhist scholar Chogyam Trungpa Rinpoche introduces this film up to the 4min marker. The meat of the film's discussion begins at the 9min marker. Also when asked how/why I got interested in math, I usually answer with words like "outdoor raves / technivals / full moon gatherings". I found mathematics on many sunrises & moonsets in deserts, farms, fields, and Pacific coast beaches--somewhere between minimal detroit house, deep house, tribal house, and hard acid techno house (see map on House) at this link. If you were one of the many beautiful souls that evolved with me through our bliss & harmony on those mornings dancing to the sunrise in Northern California, then you might recall the bass bins oozing Psychotropic Hypnosis or perhaps Frankie Knuckles' Whistle Song.
