A method to construct irreducible totally nonnegative matrices with a given Jordan canonical form

Cantó Colomina, Begoña; Cantó Colomina, Rafael; Urbano Salvador, Ana María (Servicio de Publicaciones de la Universidad de Oviedo, 2021-06-18)

[EN] Let A¿Rn×n be an irreducible totally nonnegative matrix (ITN), that is, A is irreducible with all its minors nonnegative. A triple (n,r,p) is called realizable if there exists an ITN matrix A¿Rn×n with rank(A)=r and ...
Jordan structures of irreducible totally nonnegative matrices with a prescribed sequence of the first p-indices

Cantó Colomina, Begoña; Cantó Colomina, Rafael; Urbano Salvador, Ana María (Springer-Verlag, 2022-03-19)

[EN] Let A be an nxn irreducible totally nonnegative matrix with rank r and principal rank p, that is, A is irreducible with all minors nonnegative, r is the size of the largest invertible square submatrix of A and p is ...
