MAT 319 and 320
MAT 319 (Foundations of Analysis) and MAT 320 are taught as a single lecture until
the first midterm. Based on the results of the first midterm, students may switch
into MAT 320, which will proceed at a faster pace than MAT 320. Professor Martens
will teach MAT 319, and the two of us will share lectures up until the first midterm.

Course Summary
This is a course in real analysis or roughly "calculus with proofs".
We will start by recalling set notation, the principle of induction,
and the basic properties of finite and infinite sets. We then
discuss the axioms of the real numbers, and learn to rigorously
derive various familiar properties. When then study sequences
and limits. Around this point MAT 319 and 320 will separate. In
MAT 320 will will then discuss continuity, differentiation,
Riemann integration, sequences of functions and infinite series.
If time permits, we will discuss basic point set topology,
metric spaces, the generalized Riemann integral and
the Lebesgue integral.
Time and Place
For the first few weeks, MAT 319 and MAT 320 both meet Tuesdays and
Thursdays 9:45am-11:05am in Stony Brook Union room 103-02.
After the classes split MAT will continue in that room and MAT 320 will
meet in Mathematics P-131 (this room is directly behind the elevators on the
PL level of the Math Tower). Recitations meet twice a week as follows:
MAT 319 R01 MW 11:45am-12:40pm Earth-Space Science 181, TA is Jordan Rainone
MAT 319 R02 MW 11:45am-12:40pm Frey Hall 309,
TA is Paul Sweeney
MAT 319 R03 MW 11:45am-12:40pm Socbehav Sci N310, Dylan Galt
MAT 320 R01 MW 11:45am-12:40pm Physics P116, TA is Jordan Rainone
(this meets after 1st midterm)
Note that all recitations meet at the same time.
Office Hours
TuTh 11:10-12:40 (after class) and by appointment. Meetings on
other days can be in
person or via Zoom, depending on my schedule.
Textbook
The textbook is "Introduction to Real Analysis, 4th Edition" by
Robert Bartle and Donald Sherbert.
Grades
Grades will be based on weekly problem sets, two midterms and a final exam.
Each component will count for 25% of the total grade.
SAMPLE MIDTERM 1
Final Exam
The final exam is Tuesday, December 14, 8:00am-10:45am. Location will be
be announced later. Possibly all final exams will be online.
Blackboard
Blackboard
is the Stony Brook University class management system. Your
homework, quiz and exam grades will be posted here. Letter grades
for the course are posted in the Solar System. I will occasionally
post announcements in Blackboard; you should receive email notifications
whenever this occurs.

Stony Brook Virtual SINC Site
The
Virtual Sinc Site
gives you access to various software
packages on a university license, such as Mathematica and Matlab.
I don't plan to use any of these in this class, but this resource
may be helpful in other classes.
Using the virtual Sinc Site requires downloading the
Citrix receiver software (you will be prompted).

Pass/No Credit
This policy allows you to set a threshold so that if you
score above the threshold in a class you get a that grade
on your transcript, and otherwise you get a P (for pass) or
NC (no credit), neither of which affects your GPA.
For example, if you set the threshold at C and if you get a
C- or a D you will get a P in the course (which means it won't
count towards major requirements, but also won't affect your GPA).
A grade of F gives an NC (also won't affect your GPA), and any
grade equal to or higher than your threshold will count as usual.
Generally, only one course per semester may be designated P/NC.
Check the Bulletin for precise dates and requirements; your major may
also have rules about which classes these may be used for.
SBU G/P/NC page.
Problem sets
There will be a problem set due each week (except the first week
of class and midterm weeks; sections covered the week before a
midterm are due the week after the midterm).
These should be handed in at the first recitation of the week.
Problems will be taken from the textbook and are listed in
the lecture schedule below. Problems from a section
are due in recitation the week after that section is covered
in lectura (except for midterm weeks).
Most of the problems are short proofs. In general, a few sentences will be
sufficient for most problems. A proof should be a clearly written argument;
the graders may penalize organizational or grammatical errors that make the
problem hard to read or the reasoning hard to follow. Include a diagram or
picture if this helps convey the meaning. For most problems, I would expect
that a couple of practice drafts will be necessary. It is hard
even for an experienced mathematician to write down a complete, legible proof
off the top of their heads (published proofs can take weeks, months or even
years of polishing to make the ideas understandable, but I would guess 15-30
minutes would be sufficient for most problems in this course).
