Large deviations for small noise hypoelliptic diffusion bridges on sub-Riemannian manifolds

Yuzuru Inahama

In this paper we study a large deviation principle of Freidlin-Wentzell type for pinned hypoelliptic diffusion measures associated with a natural sub-Laplacian on a compact sub-Rie…

Positivity of the density for rough differential equations

Yuzuru Inahama, Bin Pei

Due to recent developments of Malliavin calculus for rough differential equations, it is now known that, under natural assumptions, the law of a unique solution at a fixed time has…

Stochastic flows and rough differential equations on foliated spaces

Yuzuru Inahama, Kiyotaka Suzaki

Stochastic differential equations (SDEs) on compact foliated spaces were introduced a few years ago. As a corollary, a leafwise Brownian motion on a compact foliated space was obta…

Asymptotic expansion of the density for hypoelliptic rough differential equation

Yuzuru Inahama, Nobuaki Naganuma

We study a rough differential equation driven by fractional Brownian motion with Hurst parameter . Under Hörmander's condition on the coefficient vector fields…

Paracontrolled quasi-geostrophic equation with space-time white noise

Yuzuru Inahama, Yoshihiro Sawano

We study the stochastic dissipative quasi-geostrophic equation with space-time white noise on the two-dimensional torus. This equation is highly singular and basically ill-posed in…

Rough path theory and stochastic calculus

Yuzuru Inahama

T. Lyons' rough path theory is something like a deterministic version of K. Ito's theory of stochastic differential equations, combined with ideas from K. T. Chen's theory of itera…
