"Benedicks’s uncertainty principle for metaplectic Wigner disitributions"Shafkulovska, IrinaGiven a metaplectic Wigner distribution, we investigate whether there exist non-zero functions whose metaplectic Wigner distribution is supported on a set of finite measure. We study this in the sesquilinear and quadratic version and provide a full characterization of the class of metaplectic Wigner distribution which exhibit an uncertainty principle of this type. |
