Resumen:
In this topical review we discuss the
connections between chaos, decoherence and quantum cosmology. We
understand chaos as classical chaos in systems with a finite number of
degrees of freedom, decoherence as environment induced decoherence and
quantum cosmology as the theory of the Wheeler?DeWitt equation or else
the consistent history formulation thereof, first in mini super spaces
and later through its extension to midi super spaces. The overall
conclusion is that consideration of decoherence is necessary (and
probably sufficient) to sustain an interpretation of quantum cosmology
based on the wavefunction of the Universe adopting a
Wentzel?Kramers?Brillouin form for large Universes, but a definitive
account of the semiclassical transition in classically chaotic
cosmological models is not available in the literature yet.
