Professor Anthony Gaglione  


Dr. Gaglione's research is in the field of Combinatorial Group Theory. More specifically, he works in a sub-category of this field called the commutator calculus. This research has its origins in the work of Philip Hall, who invented the "Collection Process." This method and its applications mark the beginning of the commutator calculus. One of the principle applications of the collection process is the determination of the quotient groups of the lower central series of free groups of finite rank.

Recently, Dr. Gaglione has succeeded in determining "in principle" all quotient groups of the lower central series for a large class of groups. These groups are important in other areas of mathematics (e.g., algebraic topology) and also arise in many other applications. Should such a group arise in any application, it would be important to have a "description" of that group.

Dr. Gaglione has also been involved in applications of group theory to logic and to cryptography. Dr. Gaglione has numerous publications in this area.
