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 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.

Bifurcation analysis to RayleighBénard convection in finite box with updown symmetry

RayleighBénard convection in a small rectangular domain is studied
by the standard bifurcation analysis.
The dynamics on the center manifold is calculated up to
3rd order. By this normal form, it is possible to determine the local bifurcation
structures in principle. One can easily imagine that mixed mode solutions
such as hexagonal, patchworkquilt patterns are unstable from the knowledge
of amplitude equation:GinzburgLandau equation. However they are not necessarily
similar to each other in a small rectangular domain.
Several nontrivial stable mixed mode patterns are introduced.

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 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).

In the present paper we study the existence of solutions for a nonlocal Schrödinger equation
\begin{eqnarray*}
\varepsilon^2\Delta u +V(x)u =(\int_{R^3}
\frac{u^{p}}{xy^{\mu}}dy)u^{p2}u,
\end{eqnarray*}
where $0 < \mu < 3$ and $\frac{6\mu}{3} < p < {6\mu}$. Under suitable assumptions on the potential $V(x)$, if the parameter $\varepsilon$ is small enough, we prove the existence of solutions by using MountainPass Theorem.
