Real matrix-variate gamma function, real matrix-variate digamma function, logarithmically convex, inequalityAbstract
In this paper, we prove that the real matrix-variate gamma function is logarithmically convex and as a consequence, we derive some inequalities involving the function. Also, we introduce the real matrix-variate digamma function and as applications, we derive some inequalities for certain ratios of the real matrix-variate gamma function. The methods of proofs are analytical in nature.
