Abstract
It is shown that, for the scalar-tensor cosmology (STC) by Jordan-Brans-Dicke (JBD), in general anisotropic solution the oscillatory ‘mixmaster’ regime near the singularity will be destroyed by the scalar source-free field and replaced by monotonousV 3-collapse into the ‘point’ or into the ‘line’ and ‘plane’ (only in caseG→0) even in the presence of the primordial source-free electromagnetic (EM) field.
