We present an energymethodsbased proof of the existence and uniqueness of solutions of
a nonlocal aggregation equation with degenerate diffusion. The equation we study
is relevant to models of biological aggregation.

Spatially localized patterns form a representative class of patterns in dissipative systems.
We study how the dynamics of traveling spots in twodimensional space change when heterogeneities are introduced in the media.
The simplest but fundamental one is a line heterogeneity of jump type. When spots encounter the jump,
they display various outputs including penetration, rebound, and trapping depending on the incident angle and its height.
The system loses translational symmetry by the heterogeneity, but at the same time, it causes the emergence of various
types of heterogeneityinducedorderedpatterns (HIOPs) replacing the homogeneous constant
state. We study these issues by using a threecomponent reactiondiffusion system with one activator
and two inhibitors. The above outputs can be obtained through the
interaction between the HIOPs and the traveling spots.
The global bifurcation and eigenvalue behavior of HISPs are the key to understand the underlying
mechanisms for the transitions among those dynamics. A reduction to a finite dimensional
system is presented here to extract the modelindependent nature
of the dynamics. Selected numerical techniques for the bifurcation analysis are also
provided.

We consider a parametric nonlinear equation driven by the Neumann $p$Laplacian.
Using variational methods we show that when the parameter
$\lambda > \widehat{\lambda}_1$
(where $\widehat{\lambda}_1$ is the first nonzero eigenvalue of the negative Neumann $p$Laplacian),
then the problem has at least three nontrivial smooth solutions,
two of constant sign
(one positive and one negative)
and the third nodal.
In the semilinear case
(i.e., $p=2$),
using Morse theory and flow invariance argument,
we show that the problem has three nodal solutions.

In this paper, we classify the class of constant weighted curvature curves in the plane with a loglinear density, or in other words, classify all traveling curved fronts with a constant forcing term in $R^2.$ The classification gives some interesting phenomena and consequences including: the family of curves converge to a round point when the weighted curvature of curves (or equivalently the forcing term of traveling curved fronts) goes to infinity, a simple proof for a main result in [13] as well as some wellknown facts concerning to the isoperimetric problem in the plane with density $e^y.$

We are concerned with the finiteelement approximation for the KellerSegel system
that describes the aggregation of slime molds resulting from their
chemotactic features.
The scheme makes use of a semiimplicit time discretization
with a timeincrement control and BabaTabata's conservative upwind
finiteelement approximation in order to realize the positivity and
mass conservation properties. The main aim is to present error analysis
that is an application of the discrete version of the analytical semigroup theory.

We establish the global existence and uniqueness of strong solutions to the initial boundary value problem for the incompressible MHD equations in bounded smooth domains of $\mathbb R^3$ under some suitable smallness conditions. The initial density is allowed to have vacuum, in particular, it can vanish in a set of positive Lebessgue measure. More precisely, under the assumption that the production of the quantities $\\sqrt\rho_0u_0\_{L^2(\Omega)}^2+\H_0\_{L^2(\Omega)}^2$ and $\\nabla u_0\_{L^2(\Omega)}^2+\\nabla H_0\_{L^2(\Omega)}^2$ is suitably small, with the smallness depending only on the bound of the initial density and the domain, we prove that there is a unique strong solution to the Dirichlet problem of the incompressible MHD system.

We consider a semidiscrete in time relaxation scheme to
discretize a damped forced nonlinear KleinGordon Schrödinger system.
This provides us with a discrete infinitedimensional dynamical
system. We prove the existence of a finite dimensional global
attractor for this dynamical system.

The paper deals with the NavierStokes equations in a strip in
the class of spatially nondecaying (inniteenergy) solutions belonging to the
properly chosen uniformly local Sobolev spaces. The global wellposedness
and dissipativity of the NavierStokes equations in a strip in such spaces has
been rst established in [22]. However, the proof given there contains a rather
essential error and the aim of the present paper is to correct this error and to
show that the main results of [22] remain true.

In the present paper, we consider the Cauchy problem of a system of quadratic derivative nonlinear
Schrödinger equations which was introduced by M. Colin and T. Colin (2004) as a model of laserplasma interaction.
The local existence of the solution of the system in the Sobolev space $H^s$ for $s > d/2+3$ is proved by M. Colin and T. Colin.
We prove the wellposedness of the system with low regularity initial data.
For some cases, we also prove the wellposedness and the scattering at the scaling critical regularity
by using $U^2$ space and $V^2$ space which are applied to prove
the wellposedness and the scattering for KPII equation at the scaling critical regularity by Hadac, Herr and Koch (2009).
