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.

In the present paper we prove uniqueness results for weak
solutions to a class of problems whose prototype is
$d i v((1+\nabla u^2)^{(p2)/2} \nabla u)d i v(c(x) (1+u^2)^{(\tau+1)/2}) $
$+b(x) (1+\nabla u^2)^{(\sigma+1)/2}=f \ i n \ \mathcal D'(\Omega)\qquad\qquad\qquad\qquad\qquad\qquad\qquad$
$u\in W^{1,p}_0(\Omega)\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad$
where $\Omega$ is a bounded open subset of $\mathbb R^N$ $(N\ge 2)$,
$p$ is a real number $\frac{2N}{N+1}< p <+\infty$, the coefficients
$c(x)$ and $b(x)$ belong to suitable Lebesgue spaces,
$f$ is an element of the dual space $W^{1,p'}(\Omega)$ and $\tau$ and $\sigma$
are positive constants which belong to suitable intervals specified
in Theorem 2.1, Theorem 2.2 and Theorem 2.3.

In 1999 M. Eastwood has used the general construction known as the BernsteinGelfandGelfand (BGG) resolution to prove, at least in smooth situation, the equivalence of the linear elasticity complex and of the de Rham complex in $\mathbf{R}^{3}$. The main objective of this paper is to study the linear elasticity complex for general Lipschitz domains in $\mathbf{R}^{3}$ and deduce a complete Hodge orthogonal decomposition for symmetric matrix fields in $L^{2}$, counterpart of the Hodge decomposition for vector fields. As a byproduct one obtains that the finite dimensional terms of this Hodge decomposition can be interpreted in homological terms as the corresponding terms for the de Rham complex if one takes the homology with value in $RIG\cong \mathbf{R}^{6}$ as in the (BGG) resolution.

The aim of this paper is to consider the robustness of exponential
attractors for nonautonomous dynamical systems with line memory
which is expressed through convolution integrals. Some properties
useful for dealing with the memory term for nonautonomous case
are presented. Then, we illustrate the abstract results by
applying them to the nonautonomous strongly damped wave equations
with linear memory and critical nonlinearity.

We consider a nonlinear periodic problem driven by the scalar
$p$Laplacian and a nonlinearity that exhibits a $p$superlinear growth
near $\pm\infty$, but need not satisfy the AmbrosettiRabinowitz
condition.
Using minimax methods, truncations techniques and Morse theory,
we show that the problem has at least three nontrivial solutions,
two of which are of fixed sign.

This paper considers an initialboundary value problem for the evolution equation associated with the normalized $p$Laplacian. There exists a unique viscosity solution $u,$ which is globally Lipschitz continuous with respect to $t$ and locally with respect to $x.$ Moreover, we study the long time behavior of the viscosity solution $u$ and compute numerical solutions of the problem.

We study the traveling wave solutions to a reaction diffusion system
modeling the public goods game with altruistic behaviors. The
existence of the waves is derived through monotone iteration of a
pair of classical upper and lower solutions. The waves are shown to
be unique and strictly monotonic. A similar KPP wave like asymptotic
behaviors are obtained by comparison principle and exponential
dichotomy. The stability of the traveling waves with noncritical
speed is investigated by spectral analysis in the weighted Banach
spaces.

In this paper, we study a conjecture of J.Serrin and
give a partial generalized result of the work
of de Figueiredo and Felmer about Liouville type Theorem
for nonnegative solutions for an
elliptic system. We use a new type of moving plane method
introduced by ChenLiOu. Our new ingredient is the use of SteinWeiss
inequality.

Aim of this paper is to give some nonexistence results of
nontrivial solutions for the following quasilinear elliptic
equations with singular weights in $R^n\setminus \{0\}$
$ \Delta_p u+\mux^{\alpha} u^{a2}u+\lambda 
u^{q2}u+h(x)f(u) = 0 $ and
$ \Delta_p u+\mux^{\alpha} u^{p^*_\alpha2}u+\lambda  u^{q2}u+h(x)f(u)= 0, $
where $1 < p < n$, $\alpha \in [0,p]$, $a \in [p,p^*_\alpha]$,
$p_\alpha^*= p(n\alpha)/(np)$, $\lambda, \mu \in R$ and
$q \ge 1$, while $h: R^+ \to R^+_0$ and $f: R\to R$ are given
continuous functions. The main tool for deriving nonexistence
theorems for the equations is a Pohozaevtype identity. We first
show that such identity holds true for weak solutions $u$ in
$H^{1,p}(R^n)\cap C^1(R^n \setminus \{0\})$ of the first equation
and for weak solutions $u$ in $D^{1,p}(R^n)\cap
C^1(R^n \setminus \{0\})$ of the second equation. Then, under a
suitable growth condition on $f$, we prove that every weak solution
$u$ has the required regularity, so that the Pohozaevtype identity
can be applied. From this identity we derive some nonexistence
results, improving several theorems already appeared in the
literature. In particular, we discuss the case when $h$ and $f$ are
pure powers.
