Decaying Holographic Dark Energy and Emergence of Friedmann Universe
  A universe started in almost de Sitter phase with time varying holographic
dark energy corresponding to a time varying cosmological term is considered.
The time varying cosmological dark energy and the created matter are consistent
with the Einstein's equation. The general conservation law for decaying dark
energy and created matter is stated. By asuming that the initial matter were
crated in relativistic form, we have analysed the possibility of evolving the
universe from de Sitter phase to Friedmann universe.
