The Hermitian Lanczos method for Hermitian matrices has a well-known connection with a 3-term recurrence for polynomials orthogonal on a discrete subset of ℝ. This connection disappears for normal ...

We study the solvability of the equation AX + XA * = XA + A * X = I. In particular, we obtain various criteria for the normality of A in terms of Hermitian solutions of the equation which satisfy ...

KALAMAZOO—A noted scholar from Rice University will examine how matrix theory can uncover obscure relationships among members of a social network when he speaks later this month at Western Michigan ...

Cancer cells in lab cultures have not "forgotten" how to be healthy since they can be guided back into their "normal" growth program by giving them the right cues. Applying compressive force to ...
