Boundary-Moment Universality and Curvature Corrections in Random Geometric Graphs on Riemannian Manifolds

Taro Hayashi, Subaru Nomoto, Ryoichi Suzuki

Let $(M, g)$ be a smooth, closed, connected $d$ -dimensional Riemannian manifold, and let $X_{1}, \dots, X_{n}$ be i.i.d.\ with common law $f d vol_{g}$ , where $f \in C^{4} (M)$ is str…

Existence of densities and atoms for the running maximum of time-inhomogeneous jump diffusions

Takuya Nakagawa, Ryoichi Suzuki

We prove absolute continuity of the running maximum $X_{T}^{*} = sup_{0 \leq s \leq T} X_{s}$ of one-dimensional time-inhomogeneous Lévy--Itô diffusions driven by a Brownian motion and…

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

Jirô 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…
