ABSTRACT ALGEBRA Meaning and
Definition
-
Abstract algebra is a branch of mathematics that deals with the study of algebraic structures and their various mathematical operations, such as addition, subtraction, multiplication, and division. However, unlike elementary algebra, which primarily focuses on manipulating specific numbers and variables, abstract algebra takes a more generalized and conceptual approach.
In abstract algebra, the emphasis lies on the study of abstract mathematical objects, often referred to as algebraic structures or algebraic systems. These structures encompass a wide range of mathematical concepts, including groups, rings, fields, vector spaces, lattices, and more. Each algebraic structure consists of a set of elements and a collection of operations defined on those elements. These operations follow specific axioms and rules, allowing mathematicians to explore their properties and relationships.
One of the key features of abstract algebra is its ability to analyze algebraic structures regardless of the specific nature of their elements. This means that abstract algebra focuses on the patterns and properties that are common across different algebraic systems, leading to the development of powerful theories and concepts that can be applied in various fields of mathematics and beyond. The study of abstract algebra helps mathematicians to uncover fundamental concepts and structures present in diverse areas, including number theory, geometry, cryptography, computer science, and physics.
Overall, abstract algebra provides a unified and abstract approach to understanding the underlying structures and operations that lie at the heart of mathematics, making it an essential branch of study for aspiring mathematicians and scientists.
Etymology of ABSTRACT ALGEBRA
The word "abstract" comes from the Latin word "abstractus", which is the past participle of the verb "abstrahere" meaning "to draw away". It is a combination of the prefix "ab-" which denotes separation or departure, and the verb "trahere" meaning "to draw".
The term "algebra" is derived from the Arabic word "al-jabr", which refers to a mathematical technique for solving equations. This word was introduced to Europe during the Middle Ages through translations of Arabic mathematical texts.
The phrase "abstract algebra" was first used by the German mathematician Emmy Noether in the early 20th century. She used the term to describe a branch of mathematics that focuses on the study of algebraic structures in a more general and abstract manner, dealing with sets, operations, and relationships without being limited to specific numbers or variables.
