Multiple solutions for some Neumann problems in exterior domains

  • Tsing-San Hsu (a1) and Huei-Li Lin (a1)

Extract

In this paper, we show that if q(x) satisfies suitable conditions, then the Neumann problem -Δu+u = q(x)Ⅰup−2u in Ω has at least two solutions of which one is positive and the other changes sign.
