Global Representation of Lagrangian Distributions,se a convenient method allowing a global parametrization of the Lagrangian manifold Λ, and, consequently, a global representation of the fundamental solution in the formFor the sake of brevity we describe our construction for a fixed ., omitting it futher on. This paper can be regarded as a development of [3].

As in the case of the Schr?dinger operator this is a consequence of the study of the

Second Order Perturbations of Divergence Type Operators with a Spectral Gap,struct operators of this type with a spectral gap.We also report on some recent results of Alama et al. (1992) concerning spectral properties of divergence form operators .where . is a non-negative operator whose coefficients tend to zero at ∞. Here we ask for eigenvalues of . + λ., λ > 0, in a spec
