In this paper we derive matched asymptotic expansions for a solution of the Keller–Segel system in two space dimensions for which the amount of mass aggregation is 8πN, where N = 1, 2, 3, … Previously available asymptotics had been computed only for the case in which N = 1. 
Optimal criteria for blowup of radial and N-symmetric solutions of chemotaxis systems
A simple proof of concentration of mass equal to 8π ?> for blowing up N-symmetric solutions of the Keller–Segel model of chemotaxis in two dimensions with large N is given. Moreover, a criterion for
Optimal criteria for blowup of radial solutions of chemotaxis systems
A simple proof of concentration of mass equal to $8\pi$ for blowing up either radial or $N$-symmetric solutions of Keller--Segel model of chemotaxis in two dimensions is given. Moreover, a criterion
Residual vanishing for blowup solutions to 2D Smoluchowski-Poisson equation
We study Smoluchowski-Poisson equation in two space dimensions provided with Dirichlet boundary condition for the Poisson part. For this equation several profiles of blowup solution have been

We study Smoluchowski–Poisson equation in two space dimensions provided with Dirichlet boundary condition for the Poisson part. For this equation, several profiles of blowup solution have been
Global existence and boundedness for chemotaxis-Navier-Stokes systems with position-dependent sensitivity in 2D bounded domains
This paper is concerned with degenerate chemotaxis-Navier-Stokes systems with position-dependent sensitivity on a two dimensional bounded domain. It is known that in the case without a

Transition of blow-up mechanisms in k-equivariant harmonic map heat flow
In the present article, we consider blow-up phenomena appearing in k-equivariant harmonic map heat flow from to a unit sphere : Here the scalar variable u stands for latitudinal angle on from the

Measure Valued Solutions of the 2D Keller–Segel System
We develop a theory of global measure-valued solutions for the classical Keller–Segel model. These solutions are obtained considering the limit of solutions of a regularized problem. We also prove
Stability of Some Mechanisms of Chemotactic Aggregation
TLDR
It is shown using matched asymptotic methods that the consideredblow-up mechanism is stable, and small perturbations of the initial data produce a small shifting on the blow-up time and the Blow-up point but not modification in the blow -up mechanism.
The 8π‐problem for radially symmetric solutions of a chemotaxis model in the plane
The existence, uniqueness and large time behaviour of radially symmetric solutions to a chemotaxis system in the plane ℝ2 are studied either for the critical value of the mass equal to 8π or in the
Existence and asymptotic behaviour for the parabolic–parabolic Keller–Segel system with singular data
This work considers the Keller–Segel system of parabolic–parabolic type in for n ⩾ 2. We prove existence results in a new framework and with initial data in . This initial data class is larger than
Infinite time aggregation for the critical Patlak‐Keller‐Segel model in ℝ2
We analyze the two‐dimensional parabolic‐elliptic Patlak‐Keller‐Segel model in the whole Euclidean space ℝ2. Under the hypotheses of integrable initial data with finite second moment and entropy, we
Point Dynamics in a Singular Limit of the Keller--Segel Model 2: Formation of the Concentration Regions
TLDR
This paper analyzes the precise way in which the regularization introduced in the Keller--Segel system stops the aggregation process and yields the formation of concentration regions.
Conservative numerical schemes for the Keller-Segel system and numerical results (Mathematical analysis on the self-organization and self-similarity)
We summarize conservative numerical schemes for the Keller‐Segel system modelling chemotaxis. The advantage of our schemes is that they satisfy the conservation of positiv‐ ity and total mass. Both

A system of partial differential equations modelling chemotactic aggregation is analysed (Keller-Segel model). Conditions on the system of paramaters are given implying global existence of smooth
Chemotactic collapse for the Keller-Segel model
TLDR
It is shown here that there exist radial solutions exhibiting chemotactic collapse by means of matched asymptotic expansions techniques, which mean that u(r, t) →Aδ(y) as t→T for some T<∞, where A is the total concentration of the species.
