abstract:
The main aim of the paper is to study the Fredholm property, essential spectrum, 
and invertibility of some operators of the Mathematical Physics, such that the 
Schrödinger and Dirac operators with complex 
electric potentials, and Maxwell operators in absorbing at infinity media. This 
investigation is based on the limit operators method, and the uniqueness 
continuation property for the operators under consideration.
