摘要:
We formulate a notion of a double well Hamiltonian on an abstract measure space, in a way which does not depend upon the approximate degeneracy of the lowest eigenvalue as did our previous analysis of this problem. We show that our definition is stable under the addition of a potential of order unity, and use it to analyse the spectrum of a double well Schrödinger operator in a variable external field.

摘要:
Extending Rieffel's concept of strong Morita equivalence for C*‐algebras, we introduce a notion of Morita equivalence for actions by automorphisms of a given locally compact group on C*‐algebras. We show that the crossed products (respectively the reduced crossed products) associated with equivalent actions are strongly Morita equivalent. To do this, we show that Rieffel's techniques can be used in this framework, to induce covariant representations. We also prove that this Morita equivalence generalizes the outer conjugacy of actions, and reduces to it when the C*‐algebras are stable. Moreover, Connes invariantsTand Γ depend only on equivalence classes of actions.
