The discrete analog of the Fu cik spectrum for elliptic equations, namely M-matrices, is shown to have properties analogous to the continuum. In particular, the Fu cik spectrum of a M-matrix contains a continuous and decreasing curve which is symmetric with respect to the diagonal. c © 1999 Elsevier Science B.V. All rights reserved.
