A sign-changing solution for elliptic equation with sublinear term at origin
      
It is proved that the semilinear elliptic problem with zero boundary value -Δu=λu-|u|q-1u has a changing sign solution, as q∈(0,1) and λ>amp;gt;λ2, where λ2 is the second eigenvalue of the operator -Δ in the space H01(Ω).
