9am-1pm: "Math Art in neighboring countries".
One of Bruter's favorite images. Polthier: Math connects the World.
Rinus Roelofs during his "Math Art Talk" in 2011.

9:00-9:40 Claude Bruter, FRANCE: “The European Society for Mathematics and Art ‘ESMA’ and ‘Ses raisons d'être’ ”.
His first steps in the field of mathematics and art began in the 80s with the presentation of an architectural and artistic project for a public park with mathematical activities, which, maybe, will finally be realized in Russia. As part of this project, he designed and realized exhibits with educational and cultural purposes in the field of art and mathematics, and took part in their presentation, explanation and content improvement.
9:40-10:20 Konrad Polthier, GERMANY: "Mathematical Models Paper”.
For more than twenty five years Polthier promotes the field of mathematical visualizations with its own mathematical contributions including artistic images, movies and recently mathematical models papers for mathematics education. He also organizes the next meeting of the ESMA, in Berlin.
10:20-10:40 Break
10:40-11:20 Anna Hartkopf, GERMANY: "Possibilities of the surfer programme in math art, education and science communication”.
Surfer is a program designed to make everybody feel like a mathematician. The joy of letting your mathematical intuition explore the formulas and forms is not regulated by the depth of understanding. The program is a bridge between art and math. It shows the connection between algebraic equations and algebraic surfaces in an interactive and aesthetic way. In the talk, I will show you the program and several pictures that were made by artists, mathematicians, pupils and visitors of the IMAGINARY exhibitions by the Mathematisches Forschungsinstitut Oberwolfach, which were shown in over 40 cities and 7 countries.
11:20-12:00 Tom Verhoeff, THE NETHERLANDS: "Mathematics and Art with Miter Joints and 3D Turtle Geometry".
Tom Verhoeff is a leading member of the Dutch movement "Ars and mathematics" (Chair: Hans Kuiper). He closely followed the career of his father, Koos Verhoeff. In the 1980s, the latter launched a remarkable career as a mathematician sculptor. Since 2008 Tom spreads the knowledge about the mathematical work of his father through the publication of scientific articles and numerous lectures.
12:00-12:20 Break
12:20-1pm Rinus Roelofs, THE NETHERLANDS: "Findings about Leonardo da Vinci".
Rinus Roelofs graduated in 1983 as a sculptor at the art academy AKI in Enschede, with Sigurdur Gudmundson as promoter, but his interests quickly shifted towards mathematics. His affinity with the work of Leonardo da Vinci is evident from his construction project on the dome of Leonardo da Vinci, as a result of his work by Nexus in Vinci (2003). In 2010 a large Leonardo dome sculpture was realized in Arte Sella, Italy. Since 2011, he is best known to the general public as the discoverer of a mathematical error of Leonardo. He was one of the main organizers of the Bridges conference on mathematical art in 2009 in Leeuwarden. In 2013 he organizes the meeting again, this time in Enschede.

Friday, 2pm – 5pm: "Math Art from Belgium"
Xavier De Clippeleir
Seurinck's topic
2-2:40 Xavier De Clippeleir, BELGIUM: "Transforming Polyhedra".
De Clippeleir is designer and lecturer at the Design Academy Eindhoven (the Netherlands). He is fascinated by elliptic cylinders. When cut under a suitable angle the section is a circle. This property allows to make flexible chains and it led to the discovery of several transforming polyhedra (see booklet). In the field of design the geometry has been applied for toys (produced by the Swiss company Naef), tableware and furniture systems. He will explain the geometry and show the models.
2:40-3:20 Patrick Seurinck, BELGIUM: "Masaccio's Trinity fresco: the blueprint of Brunelleschian perspective?".
Architect and philosopher Patrick Seurinck holds a Ph.D. in Art History. While working as a research assistant for Prof. Marc De Mey he was introduced to the fascinating relation between art and geometry at the onset of the Renaissance. His research focuses on the interaction between 2D and 3D geometry in painting - between surface geometry as a compositional technique and perspective as a new paradigm of vision. This approach sheds a remarkable new light on the geometry at work in the Trinity fresco - and even shows a striking resemblance with the work of Jan van Eyck.
3:20-3:40 Break
3:40-4:20 Jos Leys, BELGIUM: "Math Visualization: bridging the gap".
Jos Leys, is a retired engineer fascinated by mathematical visualization. Using tools like Povray Ultrafractal and he has created thousands of images resulting from many different areas of mathematics. Together with the French mathematicians Etienne Ghys and Aurelien Alvarez, he created the two-hour movie "Dimensions" and he is now working on a new movie with the same team. Leys' work was used in many books as a cover or illustrations, or posters for various events (like on the poster for the 2011-2012 Flemish Mathematics Olympiad).
4:20-5 Johan Gielis, BELGIUM: "Bulky Links generated by Generalized Möbius Listing bodies”.
Möbius strip are iconic shapes in mathematics. Based on the "Generalized Möbius-Listing” bodies, we consider "fat nodes" and "fat links" that appear as special sections of the “Generalized Möbius-Listing” bodies. This work was done in collaboration with mathematicians Ilia Tavkelidze (Ilia Vekua Institute, Tbilisi) and Paolo Emilio Ricci (La Sapienza, Rome). Possible applications in biology will be discussed.
Friday, 5:15pm: Ingrid Daubechies deciphers Van Eyck's Mystic Lamb.

Ingrid Daubechies, world's top woman mathematician, will show how her mathematical wavelet techniques allow to solve a yet unsolved problem about Belgian's most famous painting, the Mystic Lamb by Flemish Primitives Jan and Hubert Van Eyck.
Please enroll here (choose the option Math Art Summit: lecture Ingrid Daubechies).
Note there will be free Duvel!
After her talk there is a 'social dinner' with Ingrid Daubechies; everybody is welcome, see 'Social Events'.

Information: Dirk Huylebrouck, Department of Architecture Sint-Lucas.
The contributions for the proceedings should follow the format of the Academy: Dutch version; English version. As the description is very brief, the Bridges format will be followed for all other items (figure captions, references, subtitles, ...) as pointed out here except that all text should be in Times New Roman 12 points.
