Abstract
Subject headings
Close
- It is proven that the essential spectrum of any self-adjoint operator associated with the matrix differential expression [GRAPHICS] consists of two branches. One of these branches (called regularity spectrum) can be obtained by approximating the operator by regular operators (with coefficients which are bounded near the origin), the second branch (called singularity spectrum) appears due to singularity of the coefficients.
