Half-Discrete Hilbert-Type InequalitiesIn 1934, G. H.

In 1934, G. H. Hardy et al. published a book entitled "Inequalities", in which a few theorems about Hilbert-type inequalities with homogeneous kernels of degree-one were considered. Since then, the theory of Hilbert-type discrete and integral inequalities is almost built by Prof. Bicheng Yang in their four published books.This monograph deals with half-discrete Hilbert-type inequalities. By means of building the theory of discrete and integral Hilbert-type inequalities, and applying the technique of Real Analysis and Summation Theory, some kinds of half-discrete Hilbert-type inequalities with the general homogeneous kernels and non-homogeneous kernels are built. The relating best possible constant factors are all obtained and proved. The equivalent forms, operator expressions and some kinds of reverses with the best constant factors are given. We also consider some multi-dimensional extensions and two kinds of multiple inequalities with parameters and variables, which are some extensions of the two-dimensional cases. As applications, a large number of examples with particular kernels are also discussed.The authors have been successful in applying Hilbert-type discrete and integral inequalities to the topic of half-discrete inequalities. The lemmas and theorems in this book provide an extensive account of these kinds of inequalities and operators. This book can help many readers make good progress in research on Hilbert-type inequalities and their applications.

Highly recommended
The AZURE Batana Oil Paste for Hair is a standout for anyone looking to restore and strengthen their hair naturally. It deeply nourishes the scalp, helps reduce dryness, and leaves hair noticeably softer and shinier after just a few uses. The texture is rich but manageable, and a little goes a long way. Perfect for dry, damaged, or thinning hair. this is a simple, effective addition to any hair care routine. Love it

Miracle Oil for Thicker, Healthier Hair!
I am seriously impressed with this Batana Oil Paste. It has a lovely, natural feel and has already made my hair noticeably thicker, softer, and more manageable. The fact that it's 100% pure and sustainably sourced from Honduras gives me confidence in the quality. My scalp feels nourished—a fantastic natural product!

This product did not work on my hair as it said it would
I have used this Product over three months and still haven’t seen a results, but I will order another one and see what happened with the second jar. My edges is still the same with no improvement? I was expecting a change since I read about it can grow ball spots. My edges is not completely ball but you can see a little hair there but as I use this products it did not help or change any length or anything my edges are still the same before I used the product it’s still the same after used it. I am so disappointed. Even though it didn’t help the first time I’m still gonna try it a second time just to make sure.
