TTMS20. Divisibility of LCM matrices by Totally nonnegative GCD matrices
Speaker: Dr. Kijti Rodtes, Naresuan University, Thailand
Abstract. In this talk, we show that all totally nonnegative GCD matrices are always divisors of the corresponding LCM matrices in the ring M_n(Z). We also introduce “column monotone matrices” used to construct all totally nonnegative GCD matrices.
