Paul Erdos is considered as a scientist who is very cooperative with other known scientists. The number of his coauthors is 511. By definition the Erdos number of these scientists is taken 1. The Erdos number of the scientist who coauthored with other scientist whose Erdos number is 1, is 2, etc. Currently, there are a lot of papers devoted to the Erdos number and published in authorative journals. According to the results of \u201cThe Erdos Number Project\u201d of Oakland University in the USA the Erdos number of well-known mathematicians is rather small. For example, the Erdos number of mathematicians awarded the Fields medal in averge equals 3 (see \u201cErdos Number\u201d Wikipedia). We should note that in \u201cThe Erdos Number Project\u201d of Oakland University the Erdos number of all famous prize-holders (Fields, Wolf, Abel, Seele, etc.) were shown in the form of separate lists (see: <a href=\"https:\/\/wwwp.oakland.edu\/enp\/erdpaths\/\" target=\"_blank\">https:\/\/wwwp.oakland.edu\/enp\/erdpaths\/<\/a>).<br \/>\nAccording to information of Mathematical Reviews database American Mathematical Society for this year the Erdos number of the head of \u201cFunctions Theory\u201d of IMM ANAS Vuagr Ismayilov was equal to 2.
