Geometry Search for the term Geometry in any field. Queries are case-independent.

Funct* Wildcard queries are specified by * (e.g. functions, functorial, etc.). Otherwise the search is exact.

"Topological group" Phrases (multi-words) should be set in "straight quotation marks".

au: Bourbaki & ti: Algebra Search for author and title. The and-operator & is default and can be omitted.

Chebyshev | Tschebyscheff The or-operator | allows to search for Chebyshev or Tschebyscheff.

Quasi* map* py: 1989 The resulting documents have publication year 1989.

so: Eur* J* Mat* Soc* cc: 14 Search for publications in a particular source with a Mathematics Subject Classification code (cc) in 14.

"Partial diff* eq*" ! elliptic The not-operator ! eliminates all results containing the word elliptic.

dt: b & au: Hilbert The document type is set to books; alternatively: j for journal articles, a for book articles.

Dynamical systems techniques in cosmology. An example: LQC and the Einstein static universe. (English) Zbl 1187.83082

J. Geom. Symmetry Phys. 14, 67-83 (2009).

The author has studied stability properties of the Einstein static universe in general relativity for the case of a positive cosmological constant. It is shown that loop quantum cosmology (LQC) leads to a new high energy critical point for the Einstein static model. Thus, it points out that high energy modification to general relativity modifies the big bang singularity and also the dynamical nature of the non-singular Einstein static universe.
