DESCRIPTION:he magnetic Laplacian on a Riemannian manifold is a\nmodificat
 ion of the classical Laplace-Beltrami operator\nvia a differential one-for
 m\, called the magnetic potential. In this talk\nwe will discuss a magneti
 c version of Lichnerowicz' Theorem\nproviding a spectral gap estimate betw
 een the first two eigenvalues and\nmodifications of Cheeger isoperimetric 
 constants\ninvolving the magnetic potential which lead to higher oder Chee
 ger and\nBuser type inequalities. This material is based on joint\nwork wi
 th Michela Egidi\, Carsten Lange\, Shiping Liu\, Florentin Muench\nand Ola
 f Post.
