On nonsingularity of combinations of two group invertible matrices and two tripotent matrices

Let T(1) and T(2) be two n x n tripotent matrices and c(1), c(2) two nonzero complex numbers. We mainly study the nonsingularity of combinations T = c(1)T(1) + c(2)T(2) - c(3)T(1)T(2) of two tripotent matrices T(1) and T(2), and give some formulae for the inverse of c(1)T(1) + c(2)T(2) - c(3)T(1)T(2...

Sumario:Let T(1) and T(2) be two n x n tripotent matrices and c(1), c(2) two nonzero complex numbers. We mainly study the nonsingularity of combinations T = c(1)T(1) + c(2)T(2) - c(3)T(1)T(2) of two tripotent matrices T(1) and T(2), and give some formulae for the inverse of c(1)T(1) + c(2)T(2) - c(3)T(1)T(2) under some conditions. Some of these results are given in terms of group invertible matrices. (C) 2011 Taylor & Francis
