Zusammenfassung: | The solutions of the Cauchy problem of the KdV equation on a periodic domain ,
[see formula in PDF]
possess neither the sharp Kato smoothing property,
[see formula in PDF]
nor the Kato smoothing property,
[see formula in PDF]
Considered in this article is the Cauchy problem of the following dispersive equations posed on the periodic domain , (See Eq. (1) below)
[see formula in PDF]
where
g
∈
C
∞
( ) is a real value function with the support
[see formula in PDF]
It is shown that
(1) if
ω
≠ ∅, then the solutions of the Cauchy problem (1) possess the Kato smoothing property;
(2) if
g
is a nonzero constant function, then the solutions of the Cauchy problem (1) possess the sharp Kato smoothing property. |
