Linear Algebra

In mathematics, problems can be solved by the arithmetic operators like addition, subtraction, multiplication, and division. In algebra, we represent the numbers by any letter called a variable. If these variables are of degree 1, then it is studied under linear algebra. The first-degree equations involving algebraic expressions are called linear equations. That is, if you represent it by drawing a graph you will get a straight line.

**The Sorgenfrey Line and Lower Limit Topology**

**Basis for Topology on $\mathbb{R}$:** Consider the set $\{ [a, b): \ a < b \}$ as a basis for a topology on the real number line $\mathbb{R}$.

**Lower Limit Topology:** The resulting topology from this basis is known as the lower limit topology. In this topology, each basic open set is a half-open interval $[a, b)$, where $a < b$.

**Sorgenfrey Line:** The real line endowed with the lower limit topology is referred to as the Sorgenfrey line, commonly denoted by $\mathbb{R}_l$.

Understanding topological bases such as this allows for deeper insight into different topological structures and their properties. The Sorgenfrey line, $\mathbb{R}_l$, is an essential example in topology, illustrating the utility and uniqueness of different bases for topologies.
