Recent results on generalized conjugate functions
Karl‐Heinz Elster, A. Wolf · Birkhäuser Basel eBooks · 1988
We consider several concepts of generalized conjugate functions with the aim of their comparison. To enable this a new concept of P-conjugation is introduced which contains well-known other concepts, e.g. the generalized FENCHEL-conjugation, (with coupling functional) and the Φ-conjugation as special cases. The notion of P -conjugation is based on that of polarity (as a multifunction which was considered) p.e. by Ewers/van Maaren).
