Pathwise stability for one-dimensional SDEs driven by Brownian motion and a symmetric stable process

Takuya Nakagawa, Ryoichi Suzuki

We prove quantitative pathwise stability estimates for one-dimensional stochastic differential equations driven by a common Brownian motion and a common symmetric $α$ -stable proces…

Iwasawa-Type Spectral Resultant Growth Laws for Grover Walks on Graph Towers

JirÃ´ Akahori, Taro Hayashi, Ryoichi Suzuki

Let $X_{0} \leftarrow X_{1} \leftarrow \dots$ be a $Z_{p}^{d}$ -tower of finite graphs, and let $U_{n}$ be the Grover transition matrix on $X_{n}$ . We study Iwasawa-type $p$ -adic growth l…

Automorphisms of Smooth Hypersurfaces with Fixed Loci of Codimension at Most Two

Taro Hayashi, Ryoichi Suzuki

We study automorphisms of smooth hypersurfaces in projective space $P^{n + 1}$ whose fixed loci have codimension at most two for $n \geq 2$ . While classifications of possible…

Existence of density functions for SDEs driven by pure-jump processes

Takuya Nakagawa, Ryoichi Suzuki

We verify the existence of density functions of the running maximum of a stochastic differential equation (SDE) driven by a Brownian motion and a non-truncated stable process. This…
