Announcements

Snow days and homework (posted Feb 16). Since class was again cancelled today, I have no way of collecting homework 4 from you until our next class, which will after the study break, on Tuesday, February 28. I am therefore extending the deadline for homework 4 until February 28.

Midterm (posted Feb 16). As you know, our midterm is scheduled for March 2. Since we have barely started chapter 5, the midterm will cover only Chapter 4: fields, systems of linear equations, vector spaces, examples of fields and vector spaces, linear combinations, span, subspaces, bases, the replacement lemma and its consequences, properties of bases, dimension. It will be a mixture of calculations and simple proofs.

Office hours (posted Feb 7). My current office hours are Mondays 10:30-11:30, or by appointment.

Welcome to the course (posted Jan 10). Here you will find assigments, handouts, and other up-to-date information about the course.
