Abstract:

In this study, we approach the analysis of a degenerate nonlinear functional in one dimension, accommodating a degenerate weight w. Our investigation focuses on establishing an explicit relaxation formula for a functional exhibiting p-growth for $1< p<+\infty$. We adopt the approach developed in (De Cicco, Serra Cassano), where some assumptions like doubling or Muckenhoupt conditions are dropped. Our main tools consist of proving the validity of a weighted Poincaré inequality involving an auxiliary weight.

Keywords: relaxation, degenerate variational integrals, Lower Semicontinuity, Poincaré inequalities, weight
