Functions preserving nonnegativity of matrices
Functions preserving nonnegativity of matrices
- Bangalore: Department of Mathematics, Indian Institute of Science: 2007
- The main goal of this work is to determine which entire functions preserve nonnegativity of matrices of a fixed order n — i.e., to characterize entire functions f with the property that f(A) is entrywise nonnegative for every entrywise nonnegative matrix
