Differential duality

Author

Listed:
  • A. Mantovi

Abstract

A framework for duality theory is set forth, based on the model-independent role of homotheties. An expansion vector field is introduced as global generator of pure expansion effects, in terms of which to deepen the differential aspects of preference symmetries, fundamental identities and conjugation in connection with the benchmark nature of homothetic models. Potential lines of progress are envisaged.
