Query: LIGO series, dimension of embedding and Kolmogorov's complexity   The interpretation of the series recorded by the Laser Interferometer
Gravitational Wave Observatory is a very important issue. Naturally, it is not
free of controversy. Here we apply two methods widely used in the study of
nonlinear dynamical systems, namely, the calculation of Takens' dimension of
embedding and the spectrum of Kolmogorov's complexity, to the series recorded
in event GW150914. An increase of the former and a drop of the latter are
observed, consistent with the claimed appearance of a gravitational wave. We
propose these methods as additional tools to help identifying signals of
cosmological interest.
