This manuscript discusses the existence of nontrivial weak solution for following nonlinear eigenvalue problem driven by p(?)-biharmonic operator with Rellich-type term {?(|?u|p(x)?2?u) = ?|u|q(x)?2u/?(x)2q(x), x ? ?, u ?u 0, ??. Considering case 1 < min x?? p(x) max q(x) (N 2, Np(x) N 2p(x) ), we extend corresponding result reference [8], .p(x) 2 . The proofs main results are based on mount...

On 19 September 1991 an extraordinary archaeological discovery was made at a high-altitude mountain pass (Tisenjoch, 3210 m) of the Ötztal Alps near the Austrian-Italian border. Two mountain hikers from Nürnberg, Erika and Helmut Simon, after having scaled the Finail Peak (3516 m) that day were on their way back to the Similaun mountain hut (3019 m) located at the lowest part of a mountain ridg...

he Cruise Missile Defense Advanced Concept Technology Demonstration, known as Mountain Top, was successfully completed at Kauai, Hawaii, during January and February 1996. The demonstration featured a new type of cooperative engagement known as “forward pass,” made possible by the Cooperative Engagement Capability, in which low-flying drones were engaged beyond the horizon of an Aegis ship for g...

Es t ima te s of snow grain size for the near-surface snow layer were calculated for the Tioga Pass region and Mammoth Mountain in the Sierra Nevada, California, using an inversion technique and data collected by the Airborne Visible/Infrared Imaging Spectrometer (A VIRIS). The inversion method takes advantage of the sensitivity of near-infrared snowpack reflectance to snow grain size. The Tiog...

In this article, we consider the multiplicity of solutions for nonhomogeneous Schrodinger-Poisson systems under Berestycki-Lions type conditions. With aid Ekeland's variational principle, mountain pass theorem and a Pohozaev identity, prove that system has at least two positive solutions.
