Bundles of Probability Schemes
Wai Yan Pong
We study finite probability through a category whose objects are finite probability schemes and whose morphisms are probability-preserving maps, called bundles. A bundle simultaneo…

The Integral of Secant and Stereographic Projections of Conic Sections
George Jennings, David Ni, Wai Yan Pong +1
We show that the four best-known substitutions used to integrate secant rely on different rational parametrizations of conic sections, coming from stereographic projections. We als…

Refinement of Metrics: Erdős Number, a Case Study
K. Lock, W. Y. Pong, A. Wittmond
We introduce a concept called refinement and develop two different ways of refining metrics. By applying these methods we produce several refinements of the shortest-path distance…
