具有有限光滑奇异类符号的双线性伪微分算子

Bilinear pseudo-differential operators with exotic class symbols of limited smoothness

Tomoya Kato

摘要:

我们考虑符号在双线性Hörmander类$BS_{ρ, ρ}^m$,$m \in \mathbb{R}$,$0 \leq ρ< 1$中的双线性伪微分算子.本文的目的是讨论符号的低正则性条件,以保证从$L^2 \times L^2$到$h^1$和从$L^2 \times bmo$到$L^2$的有界性.

英文摘要:

We consider bilinear pseudo-differential operators with symbols in the bilinear Hörmander class, $BS_{ρ, ρ}^m$, $m \in \mathbb{R}$, $0 \leq ρ< 1$. The aim of this paper is to discuss low regularity conditions for symbols to assure the boundedness from $L^2 \times L^2$ to $h^1$ and from $L^2 \times bmo$ to $L^2$.
