    Diagonally Singularizable Matrices
    (Addis Ababa University, 2020-06-06) Giovanni, Teumezghi; Teshome, Zelalem (PhD)
    A square matrix A is called diagonally singularizable if / A-S/ < holds for some singular matrix S (I is the identity matrix). The project brings several necessary and/or sufficient conditions for diagonal singularizability and demonstrates another specific feature, namely existence of diagonal singularizability-preserving operations and a theorem of symmetric alternative.
