RT Conference Proceedings T1 Recent results on (p,q)-Laplacian type equations A1 Bartolo, Rossella K1 Ecuaciones diferenciales AB Start ing from a new sum decomposit ion of W1,p(RN ) ∩W1,q(RN ) and usinga variat ional approach, we invest igate the existence of mult ipleweak solut ions ofa (p, q)–Laplacian equat ion on RN , for 1 < q < p < N , with a sign–changing potential and a Carath´eodory react ion term sat isfying the celebrated Ambroset t i–Rabinowitz condit ion. Our assumpt ions are mild and different from those usedin related papers and moreover our results improve or complement previous onesfor the single p–Laplacian.1 YR 2017 FD 2017-05-09 LK http://hdl.handle.net/10630/13608 UL http://hdl.handle.net/10630/13608 LA eng NO Universidad de Málaga.
