Macos 2020

International Conference on Mathematics and Computer Science
September 17-19, 2020, Braşov, Romania
4th Edition - MACOS 2020

Due to Covid-19 pandemy the Organizing Committee decided that Macos Conference will be rescheduled for September 2021.



It is our great pleasure to announce the International Conference on Mathematics and Computer Science (MACOS 2020) which will be held in Braşov, Romania, between 17th  -19th  September 2020. The conference is organized by Faculty of Mathematics and Computer Science, Transilvania University of Braşov, Romania.

Braşov is located in the central part of the country, and it is surrounded by the Carpathian Mountains. The city is at 175 km north from Bucharest. The former medieval fortress, Braşov preserves a lot from the unique charm of those times. The main attractions are Old City Hall, Council Square, Black Church, Citadel, First Romanian School and many others. Additional than Braşov city, Viscri (80 km), Sighisoara (100 km) and Biertan (146 km) represent important attractive areas for tourists.
