Modelling the composition and the dynamic of the Earth subsurface is a difficult problem, which requires the implementation of efficient numerical methods for partial differential equations and of advanced statistical methods for analyzing experimental data as well as comparing them

Decomposition of graphs, particularly decomposition into cycles, is a vibrant area of research in the intersection of graph theory and the theory of combinatorial designs. For almost two centuries, professional as well as amateur mathematicians have been intrigued by problems

Designs and codes are very active areas of research in combinatorics. There have been numerous breakthroughs in recent years, such as the existence proof for Steiner systems for arbitrary values of t. Research in designs, codes and their interaction includes
