| dc.description | Let A, B be a pair of matrices with regular inertia. If HA + A* H and HB + B*H are both positive definite for some Hermitian matrix H then all matrices in conv(A, A(-1), B, B-1) have identical regular inertia. This, in turn, implies that both conv(A, B) and conv(A, B-1) consist of non-singular matrices. In general, neither of the converse implications holds. In this paper we seek situations where they do hold, in particular, when A and B are real 2 x 2 matrices. Several aspects of the above statements for n x n matrices are discussed. A connection to the characterization of the convex hull of matrices with regular inertia is introduced. Differences between the real and the complex case are indicated. (C) 2002 Elsevier Science Inc.
