L. Glangetas et F. Merle, EXISTENCE OF SELF-SIMILAR BLOW-UP SOLUTIONS FOR ZAKHAROV EQUATION IN DIMENSION-2 .1., Communications in Mathematical Physics, 160(1), 1994, pp. 173-215
We consider the Zakharov equation in space dimension two [GRAPHICS] We
prove the existence of blow-up solutions (stable ''self-similar'' blo
w-up solutions) for this problem and we study various properties of th
ese solutions.
