I am on Fulbright--NAWI Graz Fellowship.
I am teaching a course on homological algebra
at University of Graz, Austria, and I am doing research at TU Graz.
MATH 113 Discrete Structures:
Full course for one semester. Sets, cardinality, number theory, combinatorics, probability. Proof techniques and problem solving. Additional topics may include graph theory, finite fields, and computer experimentation. Prerequisite: three years of high school mathematics. Lecture-conference.

US postage information
(not from USPS websites, they don't seem to find
this information important).
Starting 21 January 2018:
50c domestic letters, 35c domestic postcards.
I do not see new rates for international letters and postcards,
perhaps they remain the same:
115c international letters and postcards.
My wish list:
Acrobat Reader: my favorite is version 5.0 (not 8.0, not 9.0),
because it has useful hidden features
(discovered by random and concerted strokes on my keyboard).
when I need to update a pdf file (that just got texed again),
I can do cmd-w to close the window, then cmd-left arrow, and this
brings up the same corner of the page as before,
with the same magnification.
But what about my wish list: I wish that 9.0 and later would do the same,
plus, it should position the window in the same corner of the screen
as I had it carefully positioned before, not in the center of the screen
blocking out everything else.
