Upper and lower bounds for the iterates of order-preserving homogeneous maps on cones
Philip Chodrow, Cole Franks, Brian Lins
We define upper bound and lower bounds for order-preserving homogeneous of degree one maps on a proper closed cone in in terms of the cone spectral radius. We also define we…

The critical exponent for continuous conventional powers of doubly nonnegative matrices
Charles R. Johnson, Brian Lins, Olivia Walch
We prove that there exists an exponent beyond which all continuous conventional powers of n-by-n doubly nonnegative matrices are doubly nonnegative. We show that this critical expo…
