“…Our results will be stated in a quotient form, comparing between the convex function f = f (x) and its secant (1). Notice that when f is a linear function, f coincides with its secant.…”

“…Then by selecting an appropriate function, we get the results in [1] and [11]. We encourage the reader to look at the operator versions presented in the references [1] and [11], to be able to compare them with our results.…”

“…Let f (x) = x s , 0 ≤ s ≤ 1. Then f is operator concave, hence is operator log-concave [2]. Therefore, for 0 ≤ ν ≤ 1, we have f (I∇ ν X) ≥ f (I)# ν f (X), for X = A − 1 2 BA − 1 2 .…”

“…proved in [1] as a refinement and a reverse of the numerical Young's inequality a# t b ≤ a∇ t b for a, b > 0, where a# t b = a 1−t b t and a∇ t b = (1 − t)a + tb are the weighted geometric and arithmetic means. We refer the reader to [7][8][9]13,14,16] for some fresh refinements and discussion of Young's and related inequalities.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
