Open Source Math Software

  • Group Explorer - group theory visualization (but getting a little long in the tooth now… anyone interested in updating this in HTML5 for the web?)
  • Lurch - a general validation environment for mathematical reasoning in first proof courses (currently being updated for the web)
  • Model games - a simple web app for the game-theoretic semantics of predicate logic, which I use in my honors logic class

Capstone supervision

During Spring 2010, I supervised Lubka Dagorova’s honors capstone project. She created a Microsoft Excel Add-in for examining arbitrage opportunities in international stock exchanges. See more here.
