Reconnaissance geology of the Hushe and Saltoro-Kondus river valleys, Karakorum Mountains, Kashmir, Pakistan
L'autore illustra brevemente i risultati di una ricognizione geologica effettuata nelle valli Hushe, Kondus e Saltoro. Egli distingue nell'area esaminata 3 principali unità tettoniche: a) Batolite Ladak-Deosai, b) zona di sutura (melange) dello Shyok, c) Batolite assiale del Karakorum. Il primo consiste di una grande intrusione granodioritica che verso sud attraversa un complesso gneissico a sua volta attraversato da dicchi di microdiorite. Il passaggio verso la zona di melange dello Shyok è graduale....
Periodic solutions for systems with nonsmooth and partially coercive potential
In this paper we consider nonlinear periodic systems driven by the one-dimensional -Laplacian and having a nonsmooth locally Lipschitz potential. Using a variational approach based on the nonsmooth Critical Point Theory, we establish the existence of a solution. We also prove a multiplicity result based on a nonsmooth extension of the result of Brezis-Nirenberg (Brezis, H., Nirenberg, L., Remarks on finding critical points, Comm. Pure Appl. Math. 44 (1991), 939–963.) due to Kandilakis-Kourogenis-Papageorgiou...
