Let A be an infinite sign regular (SR) matrix which can be viewed as a bounded linear operator frum 1 to itself. It is proved here that if the range of A contains the sequence (..., 1,-1,1,-1,*°), then A is onto. If A7 exists, then DAD is also SR , where D is the diagonal matrix with diagonal entries alternately I and -1. In case A is totally positive (TP… CONTINUE READING
