Finally, using energy methods we prove that maximal time is actually T=+\u221e.<\/p>\n<p>&nbsp;<\/p>\n<p><b>Domenico Vuono:\u00a0<\/b>Second and third order estimates for solutions to $p$-Laplace equations.<\/p>\n<div>\n<p class=\"v1MsoNormal\"><b>Abstract:\u00a0<\/b>We consider solutions to<\/p>\n<\/div>\n<div>\n<p class=\"v1MsoNormal\">\u2002\u2002\u2002\u2002\u2002\u2002\u2002\u2002\u2002\u2002\u2002\u2002$$ &#8211; \\Delta_{p} u = f(x) \\quad \\text{in } \\Omega\\, ,$$<\/p>\n<\/div>\n<div>\n<p class=\"v1MsoNormal\">when $p$ approaches the semilinear limiting case $p=2$ and we get third order estimates. As a consequence we deduce improved regularity properties of the stress field. The results presented in this seminar are contained in a recent paper with D. Baratta and B. Sciunzi. Finally, I present a $L^\\infty$-estimate for the second derivative of the solution. This is a recent result in preparation with F.
