Depends on #1071.

Defines radiusPowUnboundedOperator with domain a suitable subset of Schwartz maps which ensure square-integrability.
This requires two slight generalizations:

  • UnboundedOperator.ofSymmetric to allow larger codomain, and
  • radiusPowOperator_apply_memHS to allow more negative power s when the Schwartz map is bounded.

One small comment, otherwise looks good to me

Makes sense - I've separated out the toFun ψ expression so that this add_floor… lemma doesn't appear in any definitions.
