| Abstract: |
| We shall discuss analyticity properties in the spatial and time
variables for solutions to the Cauchy problem of evolution equations
with analytic initial data. In particular, lower bound estimates for
the uniform radius of spatial analyticity will be presented for
several important equations including the Korteweg-de Vries
and the Camassa-Holm equations.
The talk is based on works with Professors
S. Selberg, H. Kalisch, G. Petronilho, R. Barostichi,
and Renata Figueira. |
