DESCRIPTION:In this seminar we present the stress-energy tensor as the fun
 damental object in the study of a quantum field theory on a curved backgro
 und. We discuss its convenience with respect the somehow misleading concep
 t of particles\, and also the consequences from the implicit gravitational
  interaction\, such as additional divergences even for free fields. These 
 ones suggest the development of new different renormalization techniques i
 n curved space-time\, rather than the usual normal-ordering employed in Mi
 nkowski. In this talk we will focus mainly on the so called adiabatic sche
 me\, and compare it to the DeWitt-Schwinger formalism. Some new features f
 rom the renormalization theory will be derived (conformal anomalies)\, and
  some applications in cosmology will be presented to show the power of thi
 s method.\n\nhttps://indico.ific.uv.es/event/2420/
