Symplectic fillings of asymptotically dynamically convex manifolds I
Zhengyi Zhou
We consider exact fillings with vanishing first Chern class of asymptotically dynamically convex (ADC) manifolds. We construct two structure maps on the positive symplectic cohomol…
Quotient Theorems in Polyfold Theory and -Equivariant Transversality
Zhengyi Zhou
We introduce group actions on polyfolds and polyfold bundles. We prove quotient theorems for polyfolds, when the group action has finite isotropy. We prove that the sc-Fredholm pro…
Predicting Ambulance Demand: Challenges and Methods
Zhengyi Zhou
Predicting ambulance demand accurately at a fine resolution in time and space (e.g., every hour and 1 km) is critical for staff / fleet management and dynamic deployment. There…
Predicting Ambulance Demand: a Spatio-Temporal Kernel Approach
Zhengyi Zhou, David S. Matteson
Predicting ambulance demand accurately at fine time and location scales is critical for ambulance fleet management and dynamic deployment. Large-scale datasets in this setting typi…
Predicting Melbourne Ambulance Demand using Kernel Warping
Zhengyi Zhou, David S. Matteson
Predicting ambulance demand accurately in fine resolutions in space and time is critical for ambulance fleet management and dynamic deployment. Typical challenges include data spar…
