Abstract
A generalized derivative nonlinear Schrodinger equation, iq(t)+q(xx)+2 i i(gamma-1)q(2)q(x)()+(gamma-1)(gamma-2)\q\(4)q=0, is studied by mea ns of Hirota's bilinear formalism. Soliton solutions are constructed a s quotients of Wronski-type determinants. A relationship between the b ilinear structure and gauge transformation is also discussed.
