Gamma-positivity is an elementary property that polynomials with symmetric coefficients may
have, which directly implies their unimodality. The idea behind it stems from work of Foata …

The first interesting array of numbers a typical mathematics student encounters is Pascal's
triangle, shown in Table 1.1. It has many beautiful properties, some of which we will review …

This book gives an introduction to and an overview of the methods used in the combinatorics
of pattern avoidance and pattern enumeration in set partitions, a very active area of research …

We study various methods to generate ensembles of random density matrices of a fixed size
N, obtained by partial trace of pure states on composite systems. Structured ensembles of …

We show that under suitable assumptions, we have a one-to-one correspondence between
classical groups and free quantum groups, in the compact orthogonal case. We classify the …

Let V be a finite dimensional complex vector space and W⊆ GL (V) be a finite complex
reflection group. Let Vreg be the complement in V of the reflecting hyperplanes. We prove …

The notion of parking functions was introduced by Konheim and Weiss [53] as a colorful way
to describe their work on computer storage. The parking problem can be stated as follows …

George Grätzer started writing his General Lattice Theory in 1968. It was published in 1978.
It set out “to discuss in depth the basics of general lattice theory.” Almost 900 exercises, 193 …
