COHOMOLOGY Meaning and Definition

1. Cohomology is a mathematical concept that belongs to the field of algebraic topology, a branch of mathematics that studies properties of shapes and spaces. It is a way to measure the topological obstructions that prevent a space from being smoothly deformable into another. More precisely, cohomology measures the existence of closed forms, which are differential forms or geometric objects that are closed, meaning their exterior derivative is zero.

   In cohomology theory, spaces are associated with algebraic objects called cohomology groups. These groups capture important geometric features of the space, including holes, connectivity, and orientability. The dimension of a cohomology group represents the number of independent closed forms and provides information about the number of topological obstructions.

   Cohomology can be used to distinguish spaces that have different global properties, as well as to classify and solve mathematical problems in diverse areas such as differential geometry, algebraic geometry, and mathematical physics. It allows mathematicians to extract crucial topological information and invariants from a given space, shedding light on its structure and the possibilities of smoothly deforming it into other spaces.

   Through the study of cohomology, mathematicians gain a deeper understanding of the underlying geometric properties and connections in various mathematical contexts, contributing to the development of other mathematical disciplines and providing insights into the behavior of complex shapes and structures.

Etymology of COHOMOLOGY

The word "cohomology" has a Greek origin and can be broken down into two parts: "co-" and "homology".

The prefix "co-" comes from the Greek word "koinos", meaning "common" or "joint". It is often used to indicate that something is shared or in common.

The term "homology" is derived from the Greek words "homos", meaning "same", and "logos", meaning "study" or "relation". In mathematics, "homology" generally refers to the study of structures that are similar or have the same relation.

Therefore, "cohomology" can be understood as a mathematical concept that investigates structures or relations that are commonly shared or jointly studied.
