Fenchel transform
Webysis such as inf-convolution and Fenchel conjugate play the parts that convolution and Laplace transform play in the conventional case. 1 Introduction Event graphs constitute a special class of Petri nets in which transitions admit several incoming and outgoing arcs whereas places admit single upstream and down-stream arcs. Webrespect to which the Young-Fenchel transform (conjugate operator) from T(X) to T(X*) is a homeomorphism. Our entirely geometric proof of the bicontinuity of the transform halves the length of Mosco's proof of sequential bicontinuity, and produces a stronger result for nonseparable spaces. 1. Introduction.
