Join us in Italy, Summer 2019:

1) July 3-11, Pescara, Italy: I am co-organizing the 6th Ph.D.  Summer
    School-Conference on ``Mathematical Modeling of Complex Systems".
    Please, see here for more information on the school and how to apply.
2) July 1-2, Pescara, Italy: In collaboration with the summer school and in
    preparation for it, some colleagues from Pescara and I will give a tutorial
    on information flow in directed graphs with some applications.
    See here for information.

I was awarded the (full year) 2019/20 Fulbright-Czech
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."

Teaching Winter 2019:
=============================================

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)!

General Announcement 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:
