Research contributions in the field are ...Chapter 1 The Campbell Baker Hausdorff Formula 1.1 The problem. Recall the power series: expX= 1+X+ 1 2 X2 + 1 3! X3 +··· , log(1+X) = X− 1 2 X2 + 1 3 X3 +··· . We want to study these series in a ring where convergence makes sense; for ex-journal that will be called Algebraic Combinatorics, run according to Fair Open Access Principles.

Topics include enumeration methods, permutations, partitions, partially ordered sets and lattices, Young …Chapter 2 is essentially an algebraic combinatorics, i.e., an application of com-binatorial principle to algebraic systems, including algebraic systems, multi-systems with diagrams. The algebraic structures, such as those of groups, rings, fields and modules were generalized to a combinatorial one. We also consider actions of multi-structured combinatorial configurations, through an approach based extensively on analytic methods. Generating functions are the central objects of study of the theory. Analytic combinatorics starts from an exact enumerative description of combina-torial structures by means of generating functions: these make their first appearance as
