 Title: Extensions of positive and symmetric operators

 Abstract  

 The aim of this talk is to generalize the classical concept
 
of positive and symmetric operators, and to develop a general
 
extension theory, which overcomes not only the lack of a Hilbert
 
space structure. The concept of anti-duality carries an adequate
 
structure to define positivity in a natural way, and is still general
 
enough to cover numerous important areas where the Hilbert space
 
theory cannot be applied.
