Abstract:
The definition of the weak slope of continuous functions introduced by
Degiovanni and Marzocchi (cf. [8]) and its interrelation with the notion “steepness”
of locally Lipschitz functions are discussed. A deformation lemma and a mountain
pass theorem for usco mappings are proved. The relation between these results
and the respective ones for lower semicontinuous functions (cf. [7]) is considered.
