Inertia of the matrix $[(p_i+p_j)^r]$
Rajendra Bhatia, Tanvi Jain · Journal of Spectral Theory · 2015
Let p_1, p_2, …,p_n be positive real numbers. It is well known that for all r 0 : Connections with some other matrices that arise in Loewner’s theory of operator monotone functions and in the theory of spline interpolation are discussed.
