In this article, we study properties of multilinear Fourier integral operators on weighted modulation spaces. In particular, using the theory of Gabor frames, we study boundedness of multilinear Fourier integral operators on products of weighted modulation spaces. Further, we investigate the periodic multilinear Fourier integral operator. Finally, we study continuity of bilinear pseudo-differential operators on modulation spaces for certain symbol classes, namely 𝐒𝐆 {\mathbf{SG}} -class.

调制空间上的多线性傅立叶积分算子

在本文中,我们研究加权调制空间上的多线性傅立叶积分算子的性质。特别是,利用Gabor框架理论,我们研究了加权调制空间乘积上的多线性傅里叶积分算子的有界性。此外,我们研究了周期性多线性傅里叶积分算子。最后,我们研究了某些符号类别的调制空间上双线性伪微分算子的连续性,即 𝐒𝐆 {\mathbf{SG}} -班级。
