We prove that the extended Poincaré group in (1+1) dimensions P is solvable exponential so that it belongs to type I. Its first and second cohomology groups are calculated in order to work out a classification of the relativistic elementary systems and all the irreducible unitary representations of P are constructed by the orbit method. We show that the(More)
