Barna Imre Ferenc (HUN-REN Wigner FK):
Can Rotation Solve the Hubble Puzzle?
(Subtitle: When Hydrodynamics Meets Cosmology)

After a personal introduction, I give a brief and pedagogic introduction to
a powerful tool, to the reduction mechanism which helps us to solve linear
or non-linear partial differential equations or even systems in general. As
a trivial example I show how it works on the regular diffusion equation
geting new kind
of soutions even today. This theoretical background helped us to formulate
a simple classical spherical symmetric hydrodynamical model which is
capable to describe the hypothetical dark fluid. With additional
cosmological considerations and a rotation term this model can explain the
Hubble tension problem.

Minden érdeklődőt szeretettel várunk.
