DESCRIPTION:In the context of Quantum Field Theory\, effective actions hav
 e become one of the most widespread tools for studying quantum corrections
  to classical theories introduced by the quantization process. While the e
 xplicit calculation of effective actions has proven to be highly nontrivia
 l outside of specific setups\, several perturbative approaches have been d
 eveloped\, allowing for a deeper understanding of nonclassical features of
  these systems like the Schwinger effect. One such method is the so-called
  heat kernel expansion\, particularly useful for studying the 1-loop diver
 gences and anomalies in the effective action. In this talk I will review s
 ome of the basic aspects of the 1-loop effective action definition and hea
 t kernel methods as a whole\, and additionally go over some recently devel
 oped resummation techniques for further refining the calculations associat
 ed with it.\n\n \n\nhttps://indico.ific.uv.es/event/8126/
