p-adic Monodromy of the Universal Deformation of a HW-cyclic Barsotti-Tate Group

Yichao Tian

Let k be an algebraically closed field of characteristic $p > 0$ , and $G_{0}$ be a Barsotti-Tate group (or $p$ -divisible group) over k. We denote by $S$ the "algebraic" local moduli in…

Canonical subgroups of Barsotti-Tate groups

Yichao Tian

Let $S$ be the spectrum of a complete discrete valuation ring with fraction field of characteristic 0 and perfect residue field of characteristic $p \geq 3$ . Let $G$ be a truncated…

UV-finite scalar field theory with unitarity

Pei-Ming Ho, Yi-Ya Tian

In this paper we show how to define the UV completion of a scalar field theory such that it is both UV-finite and perturbatively unitary. In the UV completed theory, the propagator…
