El principal objectiu del grup és desenvolupar tècniques de l'anàlisi matemàtica en l'àmbit de les varietats discretes amb el propòsit d'obtenir noves eines i mètodes de resolució de problemes plantejats en aquest context. Concretament, la nostra intenció és desenvolupar un càlcul vectorial discret i utilitzar tècniques de la teoria del potencial sobre varietats discretes, tant si s'ajusten al problema físic, com si representen aproximacions del medi continu. Això ens condueix a l?estudi d'operadors i resolvents, al desenvolupament dels mètodes mimètics i a l'aplicació dels resultats obtinguts en problemes de l'enginyeria, fonamentalment d'enginyeria elèctrica.

The main objective of the group is to develop mathematical analysis techniques in the context of discrete manifolds in order to obtain new tools and new methods for solving problems in this field. More precisely, we aim to introduce vector calculus and potential theory techniques for discrete manifolds, whether they correspond to physical problems or to approximations in continuum mechanics. This leads on to the study of operators and resolvents, the development of mimetic methods and the application of results to engineering, mainly electrical engineering.
