Research Interests
My
speciality is matrix theory and my research interests include: Generalizations
of Nonnegative Matrices, Perron-Frobenius Theory Generalizations and Extensions
to Cones in Hilbert and Banach Spaces, Generalizations of M-Matrices, and ODE's
on submanifolds of the Euclidean space.
