Hyperbolic partial differential equations with complex characteristics on Fourier Lebesgue spaces
Duván Cardona, William Obeng-Denteh, Frederick Opoku
The aim of this paper is to establish well-posedness properties for hyperbolic PDEs on Fourier Lebesgue spaces. We consider hyperbolic operators with complex characteristics. Since…

Boundedness of Fourier Integral Operators with complex phases on Fourier Lebesgue spaces
Duván Cardona, William Obeng-Denteh, Frederick Opoku
In this paper, we develop boundedness estimates for Fourier integral operators on Fourier Lebesgue spaces when the associated canonical relation is parametrised by a complex phase…
