Textbook
Algebra
by
Serge Lang.
You want the
new edition
published by
Springer-Verlag
as volume number 211
in the
Graduate
Texts in Mathematics series.
This book is the classic algebra textbook
for graduate courses. I used an earlier edition when I was
an undergraduate at Brown University
and a graduate student at
Harvard.
You can look at some unofficial
companion
material
for Lang's
book that was written by
one
of
my
colleagues.
See, for instance, the
errata
to printings past and present.
Syllabus
According to the
Courseweb home page for this course, we should be covering
Tensor algebras and exterior algebras,
with application to linear transformations.
Commutative ideal theory, localization. Elementary specialization and
valuation theory. Related topics in algebra.
We will begin
with a study of linear and multilinear algebra and move on to study tensor
algebras and their quotients. There seems to be a big student interest
in commutative algebra, so that will come next.
In some sense, this course could be seen as a continuation
of the Math 250A course that I taught three
semesters ago.
I taught this course once before,
in 1992-1993.
You are welcome to consult the archive
for material from my old course, including the exams.
Note that
the course was taught
on Mondays, Wednesdays and Fridays, so the midterms were
only
50
minutes long.
Homework
Homework will be assigned weekly.
Problems will be graded by
John Voight,
the Graduate Student
Instructor assigned to this course.
John has set up his own
Math 250B
Course Web Page.
