15:30<BR>Sala delle Riunioni:<BR>Taeko Yamazaki (Science University of
Tokyo)<BR>"On the global solvability for Kirchhoff equations<BR>in
exterior domain"<BR><BR>Abstract: We consider the unique global solvability of
the initial boundary<BR>value problem for the Kirchhoff equations in exterior
domain for space<BR>dimension larger or equal to 3. The following is
known: if the generalized<BR>Fourier transform of the initial data has
sufficient regularity and decays<BR>and if the data is small, then there
exists a unique global solution.<BR>The purpose of this talk is to show that if
the initial data is<BR>sufficiently small in some suitable Sobolev spaces,
then there exists a<BR>unique global
solution.</FONT><BR><BR></DIV></FONT></BODY></HTML>
