Underdetermined sets is a new type of data structures (terms) developed in Actor Prolog . ... The point is that an underdetermined set can include some indefinite rest (a tail) like a list in usual Prolog . At the same time, the order of elements of an underdetermined set can be arbitrary one and it does not affect results of unification of underdetermined sets. Moreover, Actor Prolog guarantees that a rest of an underdetermined set never contains elements that are explicitly given in the set. ...

... Paris-13): On some interactions between Combinatorics, Computer Science and Physics . We consider two aspects of the product formula for formal power series applied to combinatorial field theories. Firstly, we remark that the case when the functions involved in the product formula have a constant term is of special interest as often these functions give rise to substitutional groups. ... It is shown that this Hopf algebra originates from the formal doubling of variables in the product formula. ...
