Weyl transform and Weyl multipliers associated with locally compact abelian groups

  • R. Radha
  • N. Shravan Kumar


In this paper, we extend to the context of locally compact abelian groups, the notion of Weyl transform. We also define and characterize Weyl multipliers for certain function spaces. A dual space characterization is provided for the space of Weyl multipliers on \(L^p\) spaces. Finally we also study the twisted shift-invariant subspaces.

The authors would like to thank the unknown referee for meticulously reading the paper and giving us some valuable suggestions. The proof of Proposition 2.8 (c) was suggested by Prof. Rajaram Bhat through a personal communication. We thank Prof. Rajaram Bhat (Indian Statistical Institute, Bangalore) for his kind response to our query.
