Estimation of the instantaneous volatility
A. Alvarez, F. Panloup, M. Pontier +1
This paper is concerned with the estimation of the volatility process in a stochastic volatility model of the following form: , where denotes the log-price…
Discontinuity of the Lempert function of the spectral ball
Pascal J. Thomas, Nguyen Van Trao
We give some further criteria for continuity or discontinuity of the Lempert funtion of the spectral ball , with respect to one or both of its arguments, in terms of cyclicity…
Finite time blow-up for a one-dimensional quasilinear parabolic-parabolic chemotaxis system
Tomasz Cieślak, Philippe Laurençot
Finite time blow-up is shown to occur for solutions to a one-dimensional quasilinear parabolic-parabolic chemotaxis system as soon as the mean value of the initial condition exceed…
Finite time blow-up for radially symmetric solutions to a critical quasilinear Smoluchowski-Poisson system
Tomasz Cieślak, Philippe Laurençot
Finite time blow-up is shown to occur for radially symmetric solutions to a critical quasilinear Smoluchowski-Poisson system provided that the mass of the initial condition exceeds…
A DCCP Congestion Control Mechanism for Wired- cum-Wireless Environments
Ijaz Haider Naqvi, Tanguy Pérennou
Existing transport protocols, be it TCP, SCTP or DCCP, do not provide an efficient congestion control mechanism for heterogeneous wired-cum-wireless networks. Solutions involving i…
Proteus mirabilis swarm-colony development with drift
Philippe Laurençot, Christoph Walker
We prove a global existence result for a model describing the swarming phenomenon of the bacterium Proteus mirabilis. The model consists of an ordinary differential equation couple…
Modelling DNA at the mesoscale: a challenge for nonlinear science?
Michel Peyrard, Santiago Cuesta-Lopez, Guillaume James
When it is viewed at the scale of a base pair, DNA appears as a nonlinear lattice. Modelling its properties is a fascinating goal. The detailed experiments that can be performed on…
Regularity issues in the problem of fluid structure interaction
David Gérard-Varet, Matthieu Hillairet
We investigate the evolution of rigid bodies in a viscous incompressible fluid. The flow is governed by the 2D Navier-Stokes equations, set in a bounded domain with Dirichlet bound…
Critical mass for a Patlak-Keller-Segel model with degenerate diffusion in higher dimensions
Adrien Blanchet, José Antonio Carrillo, Philippe Laurençot
This paper is devoted to the analysis of non-negative solutions for a generalisation of the classical parabolic-elliptic Patlak-Keller-Segel system with and porous medium-l…
On standard forms of 1--dominations between knots with same Gromov volumes
Michel Boileau, Yi Ni, Shicheng Wang
Let and be two knots in 3-sphere. Say 1--dominates , if there is a proper degree 1 map $f\co E(k)\to E(k')$, between knot exterior of . Theorem: Suppose that…
Batch kernel SOM and related Laplacian methods for social network analysis
Romain Boulet, Bertrand Jouve, Fabrice Rossi +1
Large graphs are natural mathematical models for describing the structure of the data in a wide variety of fields, such as web mining, social networks, information retrieval, biolo…
