Lecture Notes on
Number Theory
================================================================
I was awarded the (full year)
2019/20 FulbrightCzech
Distinguished Professorship at the Czech Technical
University in Prague.
The Fulbright Scholar Program is "a
program of the United States Department of State
Bureau of Educational and Cultural Affairs."
"The Fulbright Distinguished Chair Awards comprise
approximately forty distinguished lecturing,
distinguished research and distinguished lecturing/research
awards ranging from three to 12 months.
Fulbright Distinguished Chair Awards are viewed as among the
most prestigious appointments in the
Fulbright Scholar Program. Candidates should be eminent
scholars and have a significant
publication and teaching record."
Unfortunately,
administrative decisions
by the dean's office of Portland State
University
made it impossible for me to accept this wonderful award. So I am in Portland during 2019/20.
Teaching SUMMER 2020 (for 20202021, see
below):
=========================================================
IMPORTANT
1: All answers on home works and exams must be
justified, even if that is not evident from
the phrasing of the question. Answers without
justification will receive partial credit at best.
IMPORTANT 2: Before
turning in exams or HW's, write your first plus last name in the
top right corner
of each sheet you turn in (even if you
staple them together)!
===============================================================
MTH 346, Number Theory
Here you can find the flyer,
syllabus, and course plan for this course. All assignments, home works, and exams
are announced in class. Note that the plan was designed
for a noncorona course. In the current situation, the
plan
may be modified substantially. For example, quizzes
may be replaced by takehomes or other alternatives.
I wrote lecture notes for a beginning graduate course on number
theory. You can find these notes here.
The topics
of these notes are more or less the same as for this course, but
the treatment is slightly more advanced. In the
course we will follow the text book. Nonetheless, you may
profit from reading my notes alongside.

Teaching 20202021:
=========================================================
Starting
this Fall: NUMBER
THEORY ::
Here is a flyer and three
months of free lecture
notes
for a newly designed course in number theory.
This a sequence of two
courses MTH 449/549 and MTH 410/510
(fall 2020 and winter 2021).
The
material is intended to give a
general overview of all branches of number theory
with an emphasis on
more geometric proofs. In
due course, we hope to
follow this up with a final course
discussing some of the many
applications of number theory.
Starting
this Fall:
DYNAMICAL SYSTEMS
::
Here is a flyer
for my
advanced course in dynamical systems MTH
621/2/3.
The emphasis
this
year
will be on surveying
the wide range
of this branch
of mathematics
and its
applications,
rather than
probing deep
theorems.
We
will use a
great
 and very
accessible 
text
written by an
eminent
mathematician
plus
some other resources
to be
determined
during the
course.
Spring
2021: DIRECTED
NETWORKS ::
Here
is a flyer containing references to
freely available lecture
notes for this
newly designed
course
describing theory and
applications of directed graphs (MTH
610, spring 2021). This is
a very current area with
applications from data science to flocking,
finance, chemical
networks
and others. In spite of its
current
relevance, good textbooks are
still very rare. So we developed our own course,
and are writing a textbook
based on this course.

General Announcements for
Students:
===============================================================
In most of my classes you will be either strongly
encouraged,
or even obliged to turn in your HW in *.pdf format based on
LATEX.
Here is a website where LATEX is explained:
