This course aims at introducing some basic
tools of Algebraic
Topology, such as singular homology and cohomology and their
relationship. For these purposes, we will recall some fundamental
topics as CW-complexes and homotopy theory. Time permitting, we will introduce persistent homology and go over some
of its recent applications to various areas.
Please find below a list of problems taken from the textbook [S]. You should return ten of them at most one week
before you take the oral exam. In addition to some questions about the
chosen problems, the exam will go over the material covered in the
Exercise 1.1.19: (iv), (vii), (v),
Exercise 1.2.33: (v), (xii), (xiii);
Exercise 1.3.11: (iv);
Exercise 1.5.19: (ii), (vii);
Exercise 1.9: 3, 5, 7, 21, 28;
Exercise 3.1.7: (iv);
Exercise 3.5.23: (ii);
Exercise 4.2.27: (ii), (iii), (iv), (v);
Exercise 5.5: 5,6;
Exercise 6.2.20: (i), (viii);
Exercise 7.4.13: (iii);
Exercise 8.1.21: (i);
Exercise 8.2.19: (i), (v);
