Enumerative and Algebraic Combinatorics in the 1960’s and 1970’s

Enumerative and Algebraic Combinatorics

Enumeration, alias counting, is the oldest mathematical subject, while Algebraic Combinatorics is one of the youngest. Some cynics claim that Algebraic Combinatorics is not really a new subject but just a new name given to Enumerative Combinatorics in order to enhance its (former) poor image, but Algebraic Combinatorics is in fact the synthesis of two opposing trends: abstraction of the concret...

Recent Advances in Algebraic and Enumerative Combinatorics

Algebraic and enumerative combinatorics is concerned with objects that have both a combinatorial and an algebraic interpretation. It is a highly active area of the mathematical sciences, with many connections and applications to other areas, including algebraic geometry, representation theory, topology, mathematical physics and statistical mechanics. Enumerative questions arise in the mathemati...

Algebraic and geometric methods in enumerative combinatorics

Enumerative combinatorics is about counting. The typical question is to find the number of objects with a given set of properties. However, enumerative combinatorics is not just about counting. In “real life”, when we talk about counting, we imagine lining up a set of objects and counting them off: 1, 2, 3, . . .. However, families of combinatorial objects do not come to us in a natural linear ...

The Reading Crisis in Iran (During the 1960s and 1970s): A Critical Discourse Analysis

Purpose: Reading is one of the challenging problems in contemporary Iran. After the Persian Constitutional Revolution (1905-1911), reading becomes one of the factors that Iranians considered it necessary for modernization and development. For this reason, most people, even who were literate, had no desire to read. This situation was unpleasant for intellectuals, publishers and cultural activist...
