After a very successful first International Summer School in Mathematics for Young Students at Bremen, Germany, last year, the second summer school will be held at Lyon, France from August 20-20, 2012. The summer school is an introduction to mathematical research topics for international students at the age of transition between high school and university. Presentations and mini-courses will be given by prominent international research mathematicians. The program for the summer school is now available. More than 200 students have applied for participation; decisions are due in early May.
