MAT 534: Algebra I
Fall 2019
Course Information

### Synopsis

The course will cover the basics of abstract algebra and is the first course in the 2-semester sequence (Algebra I, Algebra II). The lectures and homework assignments will be posted on the detailed weekly schedule. The homework problems will vary from routine to rather challenging. The use of online resources for solving the homework problems is prohibited. The schedule will be regularly updated and it is necessary to check it each week. The grades, solutions of selected homework problems and solutions to the midterm will be posted on the Blackboard. Students are expected to attend class regularly and to keep up with the material presented in the lecture and the assigned reading.
