Coalescence estimates for the corner growth model with exponential weights.
Speaker: Xiao Shen (University of Wisconsin Madison) Time: 03/04/2021, 2:00pm -2:50pm Zoom ID: 992 7853 8762 Abstract: We establish estimates for the coalescence time of semi-infinite directed geodesics in the planar corner growth model with i.i.d. exponential weights. There are four estimates: upper and lower bounds on the probabilities of both fast and slow coalescence on the correct spatial scale with exponent 3/2. […]

Optimal investment problem under behavioral setting: A Lagrange duality perspective
Speaker: Zhenyu Cui from Stevens Institute of Technology Time: 02/18/2021, 2:00pm -2:50pm Zoom ID: 992 7853 8762 Abstract:We consider the optimal investment problem with both probability distortion/weighting (e.g. inverse S-shaped probability weighting) and general non-concave utility functions (e.g. S-shape utility). The regular method to solve this type of problems is to apply the concavification technique and then […]
