The Kohn-Rossi Theorem is a result in the field of complex analysis, particularly concerning the behavior of holomorphic functions. It provides conditions under which certain types of analytic functions can be extended beyond their original domains, allowing for a deeper understanding of their properties and relationships. This theorem is significant in the study of several complex variables and has implications for partial differential equations. It helps mathematicians analyze how functions behave near the boundaries of their domains, contributing to the broader understanding of complex structures in mathematics.
