This paper establishes that nekrasov matrices retain structural properties under perron complementation, indicating robustness in mathematical physics applications.
Nekrasov matrices are widely used in mathematical physics, particularly in integrable systems and quantum field theory. In this paper, we establish that Nekrasov matrices maintain their structural properties under Perron complementation of leading principal submatrices. A numerical example illustrates the effectiveness of the theoretical result.
