Mammals and birds as ethno-indicators of change: their importance to livestock farmers in Arid Patagonia (Argentina)
(Springer, 2017-06)
This work focuses on the study of signs given to humans by domestic and wild vertebrates. These signs are interpreted culturally by settlers who live on the Central Patagonian Plateau and are taken into account in making ...
SUPERLINEAR ELLIPTIC PROBLEMS WITH SIGN CHANGING COEFFICIENTS
(WORLD SCIENTIFIC PUBL CO PTE LTDSINGAPORE, 2013-08-02)
Via variational methods, we study multiplicity of solutions for the problem {-Delta u = lambda b(x)vertical bar u vertical bar(q-2)u + au + g(x, u) in Omega, u - 0 on partial derivative Omega, where a simple example for ...
Stabilization of a light bullet in a layered Kerr medium with sign-changing nonlinearity
(Amer Physical Soc, 2004-09-01)
Using the numerical solution of the nonlinear Schrodinger equation and a variational method, it is shown that (3+1)-dimensional spatiotemporal optical solitons, known as light bullets, can be stabilized in a layered Kerr ...

GROUND STATE AND NON-GROUND STATE SOLUTIONS OF SOME STRONGLY COUPLED ELLIPTIC SYSTEMS
(AMER MATHEMATICAL SOCPROVIDENCE, 2012)
We study an elliptic system of the form Lu = vertical bar v vertical bar(p-1) v and Lv = vertical bar u vertical bar(q-1) u in Omega with homogeneous Dirichlet boundary condition, where Lu := -Delta u in the case of a ...
Mathematical videos, social semiotics and the changing classroom
(2020-10-01)
With the advancement of digital technology, the roles of teachers and students are slowly changing. The classroom is on the verge of becoming a new, more open place, one with fewer barriers to the rest of society. Our ...
