ContinuityAssume with no loss of generality that the first potentialsingularity is at t = 0andthattheinitildataisgivenatt = −1.Theorem(Geba and SGR) The equivariant solution to theAdkins-Nappi model is continuous at the originu(r,t) → 0,as(r,t) → (0,0)There is still the possibility that the solution may not bedifferentiable.To avoid that we must show that the energy does notconcentrate; and that the energy density controls all thederivatives.S.
