Title: Low regularity conservation laws for the Camassa-Holm equation and the Fokas-Lenells equation (II)
Abstract: In this talk, we will show low regularity conservation laws for the Camassa-Holm equation and the Fokas-Lenells equation in Besov spaces both on the line and on the circle. We utilize the power series expansion of the perturbation determinant associated to the Lax pair to derive low regularity a-priori estimates.
