Eventually nonnegative matrices are real matrices whose powers become and remain nonnegative. As such, eventually nonnegative matrices are, a fortiori, matrix roots of nonnegative matrices, which motivates us to study the matrix roots of nonnegative matrices. Using classical matrix function theory and Perron-Frobenius theory, in this talk we discuss how to characterize, classify, and describe, in terms of the complex and real Jordan canonical form, the pth-roots of nonnegative and eventually nonnegative matrices.
