Combinatorics on words is an area of research which has matured into a separate discipline in the last few decades. It is concerned with properties of sequences of symbols, either finite or infinite, taken from a finite alphabet. The focus on words can be algebraic, combinatorial, or algorithmic. Typical to the field is its manifold connections, not only to topics in mathematics, but also to other
scientific disciplines. Such areas inside mathematics include, for example, certain parts of algebra (e.g., combinatorial group theory and semigroups), probability theory, number theory, and discrete symbolic dynamics. Areas in other sciences include, for example, crystallography, and computational biology. Combinatorics on words has been particularly connected to and motivated by theoretical computer science, e.g., automata theory and pattern matching algorithms.
Recent breakthroughs, however, like the resolution of the decades-old Ehrenfeucht-Silberger conjecture, have led to new interest and momentum in this area.
This workshop aims to bring together world experts in the various flavours of combinatorics on words to identify, attack, and even solve some of the outstanding problems of this field.
