In this note we study the connection between the spectra of the products AB and BA of unbounded closed operators A and B acting in Banach spaces. Under the condition that the resolvent sets of these products are not empty we show that the spectra of AB and BA coincide away from zero and prove the co

## On the Spectrum of Products of Operator Ideals By HERMANN KONIG \*) of Bonn (Eingegangen am 10. 3.1978) The eigenvalues of absolutely p-summing ( 2 ~p -=-) and type lp operators (0 <p-=-) in BANACH spaces are p-th power summable. I n this note, we deal with operators which can be factored as p
## Abstract We explicitely compute the absolutely continuous spectrum of the Laplace–Beltrami operator for __p__ ‐forms for the class of warped product metrics __dσ__ ^2^ = __y__ ^2__a__^ __dy__ ^2^ + __y__ ^2__b__^ __dθ__ ^2^, where __y__ is a boundary defining function on the unit ball __B__ (0,
