We construct, for any sentence Ψ of the modal μ calculus (Lμ), a derived sentence ΨML in the modal fragment ML of Lμ and a sentence ΨΠ μ 1 in the fragment Πμ1 of Lμ without least fixpoints such that Ψ is equivalent to a formula in ML or Πμ1 if and only if it is equivalent to ΨML or ΨΠ μ

A bstract We discuss sensitivities to lepton flavor violating (and conserving) interactions at future muon colliders, especially μ + colliders. Compared with the searches for rare decays of and τ , we find that TeV-scale colliders have better depending on pattern hierarchy in mixings. As an example, study case type-II seesaw model, where mixing parameters direct relation neutrino mass matrix. A...
