Kontsevich on the Hodge and Tate conjectures
Yesterday afternoon there was an event at CUNY featuring a panel discussion on Chern-Simons terms. Nothing new there, although it was interesting to hear first-hand from Witten the story of how he came up with the Chern-Simons-Witten theory. One piece … Continue reading

The Trouble With Path Integrals, Part II
This posting is about the problems with the idea that you can simply formulate quantum mechanical systems by picking a configuration space, an action functional S on paths in this space, and evaluating path integrals of the form $$\int_{\text{paths}}e^{iS[\text{path}]}$$ Necessity … Continue reading
