Calculus, continuity and global wave-front properties for Fourier integral operators on
S. Coriasco, K. Johansson, J. Toft
We illustrate the composition properties for an extended family of SG Fourier integral operators. We prove continuity results for operators in this class with respect to and…
Young type inequalities for weighted spaces
Joachim Toft, Karoline Johansson, Stevan Pilipovic +1
We establish sharp convolution and multiplication estimates in weighted Lebesgue, Fourier Lebesgue and modulation spaces. Especially we recover some known results.
A note on products in weighted Fourier-Lebesgue spaces
Karoline Johansson, Stevan Pilipovic, Nenad Teofanov +1
We consider multiplication properties of elements in weighted Fourier Lebesgue and modulation spaces. Especially we extend some results by Pilipovic, Teofanov and Toft (2010).
Micro-local analysis in some spaces of ultradistributions
Karoline Johansson, Stevan Pilipovic, Nenad Teofanov +1
In this paper we extend some results from our earlier papers on wave-front sets, concerning wave-front sets of Fourier-Lebesgue and modulation space types, to a broader class of sp…
Generalized free time-dependent Schrödinger equation with initial data in Fourier Lebesgue spaces
Karoline Johansson
Consider the solution of the free time-dependent Schrödinger equation with initial data f. It is shown by Sjögren and Sjölin (1989) that there exists f in the Sobolev space H^s(R^d…
Association between temperate distributions and analytical functions in the context of wave-front sets
Karoline Johansson
Let B be a translation invariant Banach function space (BF-space). In this paper we prove that every temperate distribution f can be associated with a function F analytic in the co…
