  • 11:00 - 11:45. "Mathematics of kolam", Oscar García-Prada (ICMAT-CSIC)

In Tamil Nadu, a state in southern India, it is an old tradition to decorate the entrance to the home with a geometric figure called ``Kolam''. A Kolam is a geometrical line drawing composed of curved loops, drawn around a grid pattern of dots. This is typically done by women using rice flour. Kolams have connections to geometry, topology, discrete mathematics, number theory,  
algebra,  and computer science.  After reviewing a bit of its history, I will explore 
some of these connections.

  • 12:00 - 12:45. "Mathematics and art in Africa", Steven Bradlow (University of Illinois at Urbana-Champaign)

Many motifs in African decorative traditions have distinctive order.  
Mathematics provides an effective language for describing this order; conversely, 
the arts and crafts incorporate and illustrate a rich range of mathematical principles.  
We will explore this symbiosis in several examples, including Ndebele house decorations, 
Tonga basketry, and Chokwe sona sand drawings.
