The influence of Leibniz on the development of discrete mathematics

The article contains an overview of the development of Leibniz’s idea of Analysis situs in discrete mathematics. The idea of Analysis Situs contributed to the development of geometry, combinator-ics, emergence of graph theory and creation of topology in the 19th century. In the 20th century, combinatorics and graph theory formed the core of discrete mathematics. In connection with the powerful development of computer technology, discrete mathematics is now becoming the most demanded area of mathematics and demonstrates the true triumph of Leibniz's ideas.
