The 13th international, interdisciplinary conference “Nexus 20/21: Relationships Between Architecture and Mathematics” will take place 26-29 July 2021 in Kaiserslautern, Germany, presented by RCA – Research Culture in Architecture, hosted by fatuk – Faculty of Architecture, Technische Universität Kaiserslautern and Kim Williams Books. The conference will take place as an Online Conference because of the situation with COVID-19.

This important meeting is the thirteenth conference in the Nexus series, following those in 1996 (Fucecchio, Florence, Italy), 1998 (Mantua, Italy), 2000 (Ferrara, Italy), 2002 (Óbidos, Portugal), 2004 (Mexico City), 2006 (Genoa, Italy), 2008 (San Diego, USA), 2010 (Porto, Portugal), 2012 (Milan, Italy), 2014 (Ankara, Turkey), 2016 (San Sebastián – Donostia, Spain) and 2018 (Pisa, Italy).

The Nexus conferences are dedicated to explorations of the relationships between architecture and mathematics through a broad panorama of topics. Over the years since the Nexus conferences began in 1996, conference participants have presented studies of buildings both large and small, as well as entire cities and neighbourhoods, designed by great architects of the past such as Leon Battista Alberti and Andrea Palladio, and by modern masters such as Xenakis, Le Corbusier, Frei Otto and Frank Lloyd Wright, and contemporary architects such as Anna Bofill and Greg Lynn. These works are studied from the viewpoint of mathematical notions: symmetry, descriptive and projective geometry, proportion, statics, grammars, computer science, topology, algebra, fractals, and many more.
