Constructive Quantum Field Theory on Curved Surfaces and Related Topics
Jiasheng Lin
This is the Ph.D. thesis of the author. In this thesis, we construct the Quantum Field Theory (QFT) model on curved surfaces and show that it satisfies Segal's axioms (…

Entanglement Entropy and Cauchy-Hadamard Renormalization
Benoit Estienne, Jiasheng Lin
This note presents a purely geometric construction of the so-called twist-field correlation functions in Conformal Field Theory (CFT), derived from conical singularities. This appr…

The Bayes Principle and Segal Axioms for , with application to Periodic Covers
Jiasheng Lin
We construct a Gibbs state on infinite volume periodic surfaces (namely, with discrete ``time translations'') by analogy with 1-dimensional spin chains and establish the…
