# Introduction to Abstract Algebra: Group Theory

1

Introduction to Abstract Algebra: Group Theory, Learn group theory or abstract algebra in pure mathematics with examples and solved exercises.

This is an advanced level course of Introduction to Abstract Algebra with majors in Group Theory. The students who want to learn algebra at an advanced level, usually learn Introduction to Abstract Algebra: Group Theory. The course is offered for pure mathematics students in different universities around the world. However, the students who take the Introduction to Abstract Algebra: Group Theory course, are named super genius in group theory. Not so much difficult, but regular attention and interest can lead to the students in the right learning environment of mathematics. Many students around the world have their interest in learning Introduction to Abstract Algebra: Group Theory but they could’t find any proper course or instructor.

Abstract Algebra is comprised of one of the main topics which are also called Group theory. Group Theory or Group is actually the name of the fundamental four properties of mathematics that are frequently used in real analysis. We actually establish a strong background of Group Theory by defining different concepts. Proof of theorems and solutions of many examples is one of the interesting parts while studying Group Theory.

This course is filmed on a whiteboard (8 hours) and Tablet (2 hours). The length of this course is 10 hours with more than 15 sections and 100 videos. Almost every content of Group Theory has been included in this course. The students have difficulties in understanding the theorem, especially in Group Theory. Theorems have been explained with proof and examples in this course. A number of examples and exercises make this course easy for every student, even those who are taking this course the first time.

I assure all my students that they will enjoy this course. But however, if they have any difficulty then they can discuss it with me. I will answer your every question with a prompt response. One thing I will ask you is that you must see the contents sections and some free preview videos before enrolling in this course.
