This work has been partially supported by Dirección General de Investigación Científica y Técnica, under grant PB86-0005.It is shown that neither the Schrödinger equation nor the Klein-Gordon one with logarithmic nonlinearities have dissipative solutions. In the case of one-dimensional space, numerical experiments with different Cauchy data, in the nonrelativistic case, lead always to final states consisting only in oscillating gaussons.engjournal articlehttp://dx.doi.org/10.1016/0375-9601(88)90191-0http://gisc.uc3m.es/~cuesta/PDFs/PLA_128_360_88.pdfopen access536Termodinámica2213 Termodinámica
