Weyl-Type Theorems For Restrictions Of Closed Linear Unbounded Operators
by Anuradha Gupta and Karuna Mamtani

Abstract
Abstract
Keywords
Weyl-type theorems, restriction operators, semi-Fredholm operators.
Mathematics Subject Classification
(2010) Primary: 47A10, 47A11 Secondary: 47A53, 47A55.
Errata
In the statements of Theorems 6-10: The condition $0\notin iso\sigma(T) \cap \sigma_{des}(T)$ is wrong. The "intersection" must be replaced with "union".
