Resumen

Este artículo proporciona un estudio sobre la existencia de cotas a priori uniformes para soluciones positivas de problemas elípticos subcríticos (P)p        -\Delta_p u =f(u),  en  \Omega,    u = 0, sobre \partial\Omega ampliando el rango conocido de no-linealudades subcríticas para las que las soluciones positivas están acotadas a priori. Nuestros argumentos se apoyan en el método de ‘moving planes’, la identidad de Pohozaev, resultados de regularidad en W1,q para q > N, y el Teorema de Morrey. En esta parte I, cuando p = 2 demostramos que existen cotas a priori para soluciones positivas clásicas de (P)2 con f(u) = u2∗−1/[ln(e+u)]α, siendo 2∗ = 2N/(N−2), y para α> 2/(N − 2). Consideramos también dominios no-convexos, recurriendo a la transformada de Kelvin. En un siguiente artículo, parte II, extendemos nuestros resultados para sistemas elípticos Hamiltonianos (ver [22]) y al p-Laplacian (ver [10]). También estudiamos el comportamiento asintótico de las soluciones radialmente simétricas uα = uα(r) de (P)2 cuando α → 0 (ver [24]).
