Existence and regularity for solutions of quasilinear degenerate elliptic systems
Patrizia Di Gironimo, Francesco Leonetti, Marta Macrì · Nonlinear Analysis · 2024
The existence of a solution to a quasilinear system of degenerate equations is proved, assuming that the datum has an intermediate degree of summability and that the off-diagonal coefficients have a support contained in a crossed staircase set. The support required in this paper is larger than the one assumed in a previous work.
