# Finite fields

Notes from a one-week course, January 18–24, 2016, given as part of a linear-algebra winter school at the Nesin Mathematics Village.

# Geometries

*Note added after the course:* We covered projective geometry in
the first week, hyperbolic in the second. I created a text version of
the first week, with an introduction explaining the origins of the
course and what might be added to it (92 pages, size A5, 12 point type,
dated January 9, 2017):

Here is a corrected version of the Turkish Pappus text, dated
September 26, 2016 (reminder to self: I get the table on the last page
properly oriented in the pdf file by means of `pdftk
<filename>.pdf cat 1-63 64N output <newfilename>.pdf`):

Thanks to the Village for printing the Pappus and Lobachevski texts
exactly as desired: as a book of size A5, coil bound (*helezon
spiral*) and not comb bound.
Unfortunately there was one problem in the printing that I do not
understand: in the figures, some dotted and dashed lines that appear on
my computer screen just fine did not get printed. I do not know what to
do about this in future, if not to make all lines solid.

We shall study projective geometry and hyperbolic geometry from their
origins in the works of Pappus and Lobachevski respectively, September
12–25 (two weeks), 2016, at the Nesin Mathematics Village. // *Nesin Matematik Köyü'nde
12–25 Eylül (iki hafta), 2016, arasında, Pappus'un ve
Lobaçevski'nin eserlerinden ışınsal ve hiperbolik geometrileri
öğreneceğiz.*
