On Sabbatical in 2022-2023.

From June to December 2022, I was the Joseph Meyerhoff Visiting Professor at the
Weizmann Institute of Science
in Rehovot, Israel.
(Wikipedia: The Weizmann Institute of Science was ranked number 2, globally,
for research quality by the Nature Index in 2019.)

In May and June of 2023, I will be a Visiting Fellow at the Institute of Advanced
Studies of the University of Bologna in Italy, as well as a visitor at the Insubria
University in Como, Italy, and the University of Chieti-Pescara.

During the entire academic year and in the summer, I will be available through my
usual email for any students who wish to contact me.


Short Bio and Description of Research

This can be found here and here.

I am always looking for students, and in particular PhD students, interested and willing to
participate in research projects in (or related to) the areas described here. Interested students
should consult the links given in this website to my papers, lecture notes, and course


I have designed two new courses that I am very
excited to teach. Please, ask me about this material.

I am writing an ambitious set of notes covering an introduction to several areas of number
theory. Here is the flyer for the full year course. It is designed to emphasize connections
with other areas of mathematics such as analysis, algebra and complex analysis, as well
as to make some classical results accessible to a wider audience of non-specialists.

In the summer of 2019, I participated in a summer school in Italy where I gave a mini-course
on the theory of directed graphs. 
This resulted in the design of the 1 or 2 trimester course
"Directed Networks". Here is the flyer for the course. Some of the material has been worked
into slides: see
part 1, part 2, part 3, and part 4.

All this material is "work in progress"; expect errors and other shortcomings.
I appreciate if you report errors and welcome constructive criticism.
You can find my email at the top of this page.




Portland State covid policy:

Valid for all classes. Please, see here.


Teaching  Statements for all classes:

Here are links to DRC, Title IX, and Zoom-FERPA statements and a statement about
classroom requirements due to covid-19. All these statements are valid for all courses/classes.

Homework and Exam Statements:

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)!
IMPORTANT 3: While I actively encourage collaboration among students and may assign
                              take home exams on which you are allowed to collaborate:
                                    you must write your own exam yourself in your own words !!!
                              Copying, or even using something else as a template for your answers, is plagiarism
                              and will receive no credit whatsoever.


TEACHING 2023-2024:


Other General Announcements for Students:


In most of my classes you will be either strongly encouraged, or even obliged
(graduate students) to turn in your HW in *.pdf format based on LATEX.
Here is a website where LATEX is explained: 


Student Research Projects:

I have many research projects, Most are intended for 501 theses or PhD level projects.
If you are interested in doing a research project in:
Dynamical Systems, Social and Economic Networks, Coherent Motion of Flocks, Topology/Geometry,
Fractal Geometry, Discrete Mathematics, Mathematical Physics, Networks and Graph Theory,
or others, please talk to me.
