Stirling numbers are one of the most known classes of special numbers in Mathematics, especially in Combinatorics and Algebra. They were introduced by Scottish mathematician James Stirling (1692-1770) in his most important work, Differential Method with a Tract on Summation and Interpolation of Infinite Series (1730). Stirling numbers have a rich history; many arithmetic, number-theoretical, analytical and combinatorial connections; numerous classical properties; as well as many modern applications.

 

This book collects much of the scattered material on the two subclasses of Stirling numbers to provide a holistic overview of the topic. From the combinatorial point of view, Stirling numbers of the second kind, S(n, k), count the number of ways to partition a set of n different objects (i.e., a given n-set) into k non-empty subsets. Stirling numbers of the first kind, s(n, k), give the number of permutations of n elements with k disjoint cycles. Both subclasses of Stirling numbers play an important role in Algebra: they form the coefficients, connecting well-known sets of polynomials.

 

This book is suitable for students and professionals, providing a broad perspective of the theory of this class of special numbers, and many generalisations and relatives of Stirling numbers, including Bell numbers and Lah numbers. Throughout the book, readers are provided exercises to test and cement their understanding.

Essential household item with great quality
These Q-tips cotton swabs are a household essential that I always keep stocked. The 100% cotton tips are soft yet sturdy and perfect for so many uses from beauty to first aid. The 500 count package is a great value and lasts a long time. I appreciate the quality and consistency of the original Q-tips brand. These are far superior to generic cotton swabs in terms of quality and durability.

I only trust Q-Tip brand!! Great product. Never had luck with generic swabs.
I only trust Q-Tip brand!! This is a consistently great product. I've never had good luck with generic swabs, they either bend, don't have enough cotton on the end, or fray as I use them. These are soft tips, yet the stick is firm enough not to bend. I'll always go with Q-Tips and this 500 pack is a great value.

Soft, Effective, and Great for Everyday Use
I’ve been using these cotton pads for a few weeks and overall I’m very pleased with them. The softness is one of the first things I noticed—they feel gentle on my skin and don’t cause irritation, even around the eye area. They work well for makeup removal and hold cleanser or micellar water without falling apart. The absorbency is good, though they do soak up a little more product than I would prefer. The cotton content feels high quality, and the pads maintain their shape during use. Another thing I appreciated is that they leave very little residue behind compared to some cheaper alternatives that shed fibers all over your face. For the price, I think they offer solid value for money, especially considering the quality and comfort. The only reason I’m giving 4 instead of 5 stars is that I wish they were slightly less absorbent so less product would be wasted. Other than that, they’re a reliable addition to my skincare routine and I would purchase them again.
