International School on Fundamental Crystallography
Fifth MaThCryst school in Latin America
Workshop on nanocrystallography

Havana, Cuba, 30 October - 5 November 2016

Change of date

The Commission on Mathematical and Theoretical Crystallography is strongly committed to promote education in all the fundamental aspects of crystallography that nowadays are overlooked in common University courses.This mission is accomplished through a series of meetings in a wide range of regions. In fall 2016we organize a school in Havana, where the series started in 2007, followed by schools in Montevideo, in Uberlândia and in La Plata.

Posters exhibition

Monday, October 31 to Saturday, November 5

Venue

ISFC5 and workshop will be held at the Universidad des la Habana. Detailed information will follow.

Language

The official language of the school is English but the presence of Spanish speaking tutors familiarized in advance with the lectures will provid assistance to those needing it by translation or answering questions on the topic.
