The stabilization problem of positive linear discrete-time systems (PLDS) by linear state feedback is considered. A method based on a Brauer's theorem is proposed for solving the problem. It allows us to modify some eigenvalues of the system without changing the rest of them. The problem is studied for the single-input single-output (SISO) and for(More)
An n × n real matrix A is said to be (totally negative) totally nonpositive if every minor is (negative) nonpositive. In this paper, we study the properties of a totally nonpositive matrix and characterize the case of a nonsingular totally nonpositive matrix A, with a 11 < 0 in terms of its LDU factorization (L(U)) is a unit lower-(upper-) triangular(More)
The forest surface at the Valencian Community ascends to 1.247.090 hectares, which represents the 53.6 % of the total surface of the Valencian territory (2.327.194 hectares) and indicates that our community has a doubtless forest character. In fact, the hunting constitutes one of the forest activities of higher socioeconomic importance, setting in the third(More)
