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. ...

A. Singh Institute of Mathematical Sciences, C.I.T. Chennai, India anupamk18@gmail.com Real elements in algebraic groups Let G be an algebraic group defined over a field k . ... Let G be a connected semisimple algebraic group of adjoint type defined over a perfect field k . ... It follows that if G is connected semisimple of adjoint type, with -1 in its Weyl group, then every semisimple element in G(k ) is strongly real in G(k ). This also shows that any regular element in such a group is real. ...
