About 15 University students and professors crowded into a Lockett Hall classroom Thursday evening to watch and listen as Stephen Sawin, professor and notable mathematician at Fairfield University, lecture on a few math topics.The lecture included Sawin’s modern perspective on the mathematical theories, including supersymmetry, quantum mechanics and Gauss-Bonnet-Chern theorem, by using mathematical equations, containing physics and geometry to develop a construction of the path integral.”Math is a wrap onto how the universe behaves,” Sawin said. “These topics are just a warmup for students to understand the harder questions that come from physics.”According to Sawin’s specialty in these mathematical fields, supersymmetry is a theory that governs how particles interact in the world. Quantum mechanics is an idea that relates to the string theory, which combines quantum mechanics and how physics should work.Ambar Sengupta, University professor, said the Gauss-Bonnet-Chern theorem is “a very beautiful idea” to him.”It is a very important theorem in math,” Sengupta said. “But Sawin’s perspective on this classical idea is more modern and surprising.”After lecturing on these topics, Sawin said students and professors should remember that it’s possible, in some cases, to understand and come up with the path integral of time.It took Sawin and his colleague, Dana Fine,, about four years to come up with their perspectives and equations on supersymmetry, quantum mechanics and the Gauss-Bonnet-Chern theorem.Sawin has also published  several articles in the American Journal of Mathematics, including Witten’s Nonabelian Localization for Noncompact Hamiltonian Spaces, Subfactors Constructed from Quantum Group and Relative Commutants of Hecke Algebra Subfactors.—-Contact Kimberly Brown at [email protected]
