SUMMARY:Hyperbolic and Mixed Type PDEs Seminar - Some ill-posed problems in
free-surface fluid dynamics
DESCRIPTION:Seminar: Hyperbolic and Mixed Type PDEs Seminar\nTitle: Some il
l-posed problems in free-surface fluid dynamics\nSpeaker: David Ambrose\,
Drexel University\nAbstract: Certain problems in free-surface fluid dynami
cs are famously known to have ill-posed initial value problems. For the u
nregularized vortex sheet and for certain Boussinesq equations\, the ill-p
osedness is suggested by linear theory. We will discuss proofs that the f
ull systems have ill-posed initial value problems. For the vortex sheet\,
we will discuss older work of Duchon and Robert or Caflisch and Orellana
\, and we will see how the Duchon-Robert approach can be adapted to the Bo
ussinesq case. Ill-posedness can also arise for certain problems more sub
tly\, and we will discuss the ill-posedness of the initial value problem f
or truncated series models of water waves\; this is related to the numeric
al method of Craig and Sulem for water waves. The truncated series models
are linearly well-posed\, and the full water wave equations are also well
-posed\, but we will present evidence (and discuss progress towards a proo
f) that these model equations are not well-posed.

SUMMARY:Hyperbolic and Mixed Type PDEs Seminar - Some geometric aspects of
hyperbolic conservation laws
DESCRIPTION:Seminar: Hyperbolic and Mixed Type PDEs Seminar\nTitle: Some ge
ometric aspects of hyperbolic conservation laws\nSpeaker: Mike Benfield\,
North Carolina State University\nAbstract: In studying blowup solutions of
hyperbolic conservation laws\, it is of interest to find conservation law
s with certain prescribed rarefaction curves. This amounts to finding a ve
ctor field whose Jacobian matrix has prescribed eigenvector fields. Such p
roblems lead to overdetermined systems of first order PDEs\, which can be
addressed using geometric methods. Here we review some existing results an
d present new results for the case of prescribing two eigenvectors in thre
e dimensions.

SUMMARY:Hyperbolic and Mixed Type PDEs Seminar - Traveling wave solutions f
or models of collective movements with degenerate diffusivities
DESCRIPTION:Seminar: Hyperbolic and Mixed Type PDEs Seminar\nTitle: Traveli
ng wave solutions for models of collective movements with degenerate diffu
sivities\nSpeaker: Andrea Corli\, Department of Mathematics and Computer S
cience\, University of Ferrara\nAbstract: The talk deals with a nonhomogen
eous scalar parabolic equation with possibly degenerate diffusion term\; t
he process has one stationary state. The equation can be roughly interpret
ed as modeling collective movements (crowd dynamics\, for instance). Exist
ence of semi-wavefront solutions for every wave speed is established and t
heir properties are investigated. Then\, a family of traveling wave soluti
ons is constructed by a suitable combination of the previous semi-wavefron
t solutions. Several extensions of the model are then discussed. Proofs ex
ploit comparison-type techniques.

DESCRIPTION:Seminar: Hyperbolic and Mixed Type PDEs Seminar\nTitle: Uniquen
ess for a non--linear 1D compressible to incompressible limit in the non s
mooth case\nSpeaker: Graziano Guerra\, Department of Mathematics and Appli
cations\, University of Milan (Italy)\nAbstract: In the first part of the
talk we introduce some local existence and\nuniqueness results for systems
of partial and ordinary\ndifferential equations coupled through boundary
conditions.\n\nThen we introduce the problem of the compressible to incomp
ressible\nlimit for a 1D fluid (the "liquid") with finite mass m\nsurround
ed by a 1D fluid (the "gas") and we show the\nexistence of the limit\, def
ined for all times\, through a compactness argument.\n\nFinally\, since th
is limit satisfies a system of\npartial and ordinary differential equation
s\, coupled through suitable\nboundary conditions\, we can show uniqueness
.\nMoreover\, since this limit is defined for all\ntimes\, we also have th
e existence for all times of the solution to\nthis particular coupled syst
em ODE-PDE."

DESCRIPTION:Seminar: Hyperbolic and Mixed Type PDEs Seminar\nTitle: $L^1$ e
rror estimates for balance laws with space-dependent source\nSpeaker: Debo
ra Amadori\, University of L'Aquila Italy\nAbstract: This talk will concer
n the approximation of balance laws in one space dimension.\nThe aim is to
present an approach for proving rigorous $L^1$ error estimates\nfor certa
in classes of approximations\, showing the dependence on significant param
eters of the problem.\nWe focus on semilinear systems of two equation\, wi
th a space-dependent\, weakly dissipative source term\, that\ninclude the
locally damped semilinear wave equation.\nThe analysis relies on a suitabl
e modification of the original Bressan-Liu-Yang $L^1$-stability theory\nin
order to properly handle the inhomogeneity of the system.\nJoint work wit
h L. Gosse (IAC--CNR\, Rome\, Italy).
