The Symposium is dedicated to the 100th anniversary of the outstanding theoretician in the gravity theory and mathematician Alexei Zinovievich Petrov (1910-1972).  Topics of this year’s symposium include dark matter and dark energy, matter/antimatter asymmetry, early universe and particle cosmology, nonstandard cosmology, neutrino physics and astrophysics, ultra high energy cosmic rays and gamma ray bursts, large and small scale structure formation, CMB, supernovae, weak lensing, large scale structure, slow roll and fast roll inflation in connection with the CMB and LSS data, quadrupole suppression, initial conditions and low CMB multipoles, and CMB polarization.

The fourth international Symposium on High Energy Physics, Cosmology, and Gravity is organized by the Austrian Academy of Sciences (Austria), Bogolyubov Institute for Theoretical Physics of the National Academy of Sciences of Ukraine, Walter Thirring International Institute for Mathematical Physics, Astrophysics and Nuclear Investigations (Ukraine), Austro-Ukrainian Institute for Science and Technology (Austria), Slovak Research Centre (Slovakia), Czech Research Centre (Czech Republic), and Vienna University of Technology (Austria).
