This is an archive of courses I have recently
taught. Each course has a very
brief summary. If an instructor would like my course materials or
course webpage for use in a future semester, I am happy to provide it. But
since I often reuse problems, etc., I do ask that these materials
be shared with students wisely.

and on Tuesday, September 11th at the beginning of lecture for LEC02.
Section 1.1: 6, 12, 26, 30, 36
Typically problem sets will be due on Friday for LEC01 and on Thursday
for LEC02. However this week has a holiday. Problem Set 1 is a
halfproblem set.
Problem Set 2 is
due on Friday, September 21st at the beginning of lecture for LEC01
and on Thursday, September 20th at the beginning of lecture for LEC02.
Section 1.2: 10, 18, 26, 36, 46
Section 1.3: 6, 14, 30, 44, 62
Problem Set 3 is due on Friday, September
28th at the beginning of lecture for LEC01 and on Thursday, September
27th at the beginning of lecture for LEC02.
Section 2.1: 6, 10, 14, 42, 44, 48
Section 2.2: 4, 10, 26(a)(d), 44
Problem Set 4 is due on Friday, October
5th at the beginning of lecture for LEC01 and on Thursday, October
4th at the beginning of lecture for LEC02.
Section 2.3: 10, 12, 28, 42, 44

Problem Set 6 is a halfproblem
set
due on Friday, October
19th at the beginning of lecture for LEC01 and on Thursday, October
18th at the beginning of lecture for LEC02.
Section 3.3: 46, 54
Section 3.4: 56, 64, 70
Problem Set 7 is due on Friday, October
26th at the beginning of lecture for LEC01 and on Thursday, October
25th at the beginning of lecture for LEC02.
Section 3.4: 36, 54, 62, 66
Section 4.1: 16, 20, 36, 38, 40, 42
Problem Set 8 is due on Friday, November
2nd at the beginning of lecture for LEC01 and on Thursday, November
1st at the beginning of lecture for LEC02.
Section 4.2: 14, 28, 36 (but you do not have to decide if
this is an isomorphism), 44, 70
Section 4.3: 7 (the answer is in the back of the book), 8, 42, 68
(c)(e) only, 71
Originally Problem 71 was assigned as Problem 72 (since I thought
Problem 71 was worked for you in the back of the book). Since Problem
71 is not worked for you, I decided it is more fair to ask you about
Problem 71 rather than Problem 72.
Here is a hint: Compare Problem 71 in Section 4.3 with
Problem 70 in Section 4.2 (where n goes to n1 and the real
numbers a_{1},…,a_{n} go to
c_{0},…,c_{n1}).
When the linear
transformation T from Problem 70 is invertible, how does that help
prove the "weights" $w_{1},…,w_{n} do exist? How can you find the
weights, assuming you know T^{1}?
Problem Set 9 is due on Friday, November
9th at the beginning of lecture for LEC01 and on Thursday, November
8th at the beginning of lecture for LEC02. This problem set has fewer
theoretical problems and more computational problems. Hopefully this
will be helpful in studying for next week's exam.
Section 5.1: 2, 10, 16, 26, 36
Section 5.2: 14, 28, 32, 36, 42
Problem Set 10 is a halfproblem
set
due on Friday, November 16th
at the beginning of lecture for LEC01 and on Thursday, November
15th at the beginning of lecture for LEC02.

Problem Set 10 is
due in the Thursday lecture the week of Nov. 30th — Dec. 4th.
Main Problem. Let G and G'
be groups with the same finite order n.
Let m be some integer divisor of n, and assume that G and G' each
contain a unique normal subgroup P, resp. P', of order m. For each
group, consider the associated group which is the centralizer of P,
resp. P', modulo the center of P, resp. the center of P'. If G and G'
are isomorphic, prove that these associated groups are also
isomorphic.
Next, assume that there exists a subgroup Q of G which intersects P in
only the identity element and such that P and Q generate G, i.e., G is
a semidirect product of P and Q.
Let f denote the induced homomorphism from Q to the outer
automorphism group of P (not the usual homomorphism to the
automorphism group of P). Show that the kernel of f is canonically
isomorphic to the quotient of the centralizer of P by the center of
P. Thus the isomorphism class of the kernel of f is an isomorphism
invariant of G. In particular, observe that the hypotheses hold if we
restrict to groups G and G' which are each a
semidirect product of a fixed finite pgroup P and a fixed group Q
whose order is less than p+1. Moreover, if P is abelian then the
outer automorphism group of P equals the usual automorphism group of P
so that f is the usual homomorphism.
Second Problem. For every problem on Midterm 2
where you lost points, please write up a complete, correct solution to
that problem (if you only lost points on a part of the problem, you
can write up just the solution for that part). If you got full credit
on the exam, you do not need to write up anything (you will
automatically get credit for this part of the homework assignment).

Disability Support Services
If you have a physical, psychological, medical, or
learning disability that may impact your course work, please contact
Disability Support Services (631) 6326748 or
http://studentaffairs.stonybrook.edu/dss/. They will determine with
you what accommodations are necessary and appropriate. All
information and documentation is confidential.
Students who require assistance during emergency evacuation are
encouraged to discuss their needs with their professors and Disability
Support Services. For procedures and information go to the following
website: http://www.sunysb.edu/facilities/ehs/fire/disabilities.
Academic Integrity
Each student must pursue his or her academic goals honestly and be
personally accountable for all submitted work. Representing another
person's work as your own is always wrong. Faculty are required to
report any suspected instance of academic dishonesty to the Academic
Judiciary. For more comprehensive information on academic integrity,
including categories of academic dishonesty, please refer to the
academic judiciary website at
http://www.stonybrook.edu/uaa/academicjudiciary/.
Critical Incident Management
Stony Brook University expects students to respect the rights,
privileges, and property of other people. Faculty are required to
report to the Office of Judicial Affairs any disruptive behavior that
interrupts their ability to teach, compromises the safety of the
learning environment, and/or inhibits students' ability to learn.
