Query: Oscillating cosmological solutions within gauge theories of gravity   New type of nonsingular oscillating solutions for the Universe described by
cosmological equations of gauge theories of gravity is presented. Advantages of
these solutions with respect to existing nonsingular solutions within framework
of general relativity and gauge gravity are discussed. It is shown in
particular that these solutions have nonzero measure and stable on contraction
stage unlike usual nonsingular solutions.
