Scientific paper

The quantum entropies due to the scalar and Dirac fields are
investigated in a pure de Sitter spacetime. The leading divergent terms
in both cases are regularized by the Pauli-Villars scheme. It is shown
that the explosive entropies can be renormalized according to the
Bekenstein-Hawking formula.
