However after attending lectures by Luzin and Egorov at the University of Moscow he began to concentrate on mathematics. Urysohn graduated in 1919 and became an assistant professor at the University of Moscow in 1921. Hilbert Urysohn collaborated with Aleksandrov and most of his important work was only published after his death at a very young age. His main results are the introduction and investigation of a class of normal surfaces, metrization theorems and the theory of dimensionality. He is remembered particuarly for 'Urysohn's lemma' which proves the existence of a certain continuous function taking values and 1 on particular closed subsets. In the summer of 1924 he set off on a European trip through Germany, Holland and France. He met Brouwer and Hausdorff who were impressed with Urysohn's results. After this he continued his holiday to Brittany where he drowned off the coast.

There are a number of good books available but Willard is the closest to the way I want to handle the material. In Math 417 we covered most of the material in Chapters 1,2,4,5,6 of Kaplansky's Set Theory and Metric Spaces . Topics we skipped will be covered in Math 418. We have also covered Sections 1.1-3.7, as well as some material from Chapter 7 of Willard's text. You should probably quickly read Sec. 1.1-3.7 of Willard, to warm up and to get used to the book. Topics for Math 418 include connectedness, products and quotients, embedding theorems, separation axioms, some of the major classical theorems of general topology (for example, Urysohn's Lemma, Tietze's Extension Theorem, and the Tychonoff Product Theorem), and some additional set theory (ordinal numbers and transfinite methods such as transfinite induction and Zorn's Lemma), and compactifications. If time permits, we may also do a brief look at some "nonstandard" analysis (theory of infinitesimals) as an interesting "application" of set theoretic methods. Exams As in Math 417, there will be the equivalent of four exams:

The most common way, other than Aleksandrov, is to write it as Alexandroff. Pavel Sergeevich Aleksandrov's father Aleksandr Aleksandrovich Aleksandrov was a medical graduate from Moscow University who had decided not to follow an academic career but instead had chosen to use his skills in helping people and so he worked as a general practitioner in Yaroslavskii. Later he worked in more senior positions in a hospital in Bogorodskii, which is where he was when Pavel Sergeevich was born. When Pavel Sergeevich was one year old his father moved to Smolensk State hospital, where he was to earn the reputation of being a very fine surgeon, and the family lived from this time in Smolensk. The city of Smolensk is on the Dnieper River 420 km west of Moscow. Pavel Sergeevich's early education was from his mother, Tsezariya Akimovna Aleksandrova, who applied all her considerable talents to bringing up and educating her children. It was from her that Aleksandrov learnt French and also German. His home was one that was always filled with music as his brothers and sisters all great talent in that area.
