On the geometry and topology of initial data sets in General Relativity
CMSA 20 Garden Street, Cambridge, MA, United StatesSpeaker: Greg Galloway (University of Miami) Title: On the geometry and topology of initial data sets in General Relativity Abstract: A theme of long standing interest (to the speaker!) concerns the relationship between the topology of spacetime and the occurrence of singularities (causal geodesic incompleteness). Many results concerning this center around the notion of topological censorship, which […]
Workshop on Mirror Symmetry and Stability
CMSA 20 Garden Street, Cambridge, MA, United StatesThis three-day workshop will take place at Harvard University on March 18-20, 2019 in Science Center room 507. The main topic will be stability conditions in homological mirror symmetry. This workshop is funded by the Simons Collaboration in Homological Mirror Symmetry.

Quality Externalities on Platforms: The Case of Airbnb
CMSA 20 Garden Street, Cambridge, MA, United StatesSpeaker: Sonia Jaffe (Microsoft) Title: Quality Externalities on Platforms: The Case of Airbnb Abstract: We explore quality externalities on platforms: when buyers have limited information, a seller's quality affects whether her buyers return to the platform, thereby impacting other sellers' future business. We propose an intuitive measure of this externality, applicable across a range of platforms. Guest Return […]
Machine Learning for Multiscale Model Reduction Workshop
VirtualThe Machine Learning for Multiscale Model Reduction Workshop will take place on March 27-29, 2019. This is the second of two workshops organized by Michael Brenner, Shmuel Rubinstein, and Tom Hou. The first, Fluid turbulence and Singularities of the Euler/ Navier Stokes equations, will take place on March 13-15, 2019. Both workshops will be held in room G10 of the CMSA, located at 20 Garden Street, Cambridge, […]
Hyperbolic geometry of the olfactory space
CMSA 20 Garden Street, Cambridge, MA, United StatesSpeaker: Tatyana Sharpee (Salk Institute for Biological Studies) Title: Hyperbolic geometry of the olfactory space Abstract: The sense of smell can be used to avoid poisons or estimate a food’s nutrition content because biochemical reactions create many by-products. Thus, the presence of certain bacteria in the food becomes associated with the emission of certain volatile compounds. This perspective suggests that […]
