The Keller--Segel System on the Two-Dimensional-Hyperbolic Space
Autor: Vittoria Pierfelice, Patrick Maheux
Publikováno v: SIAM Journal on Mathematical Analysis. 52:5036-5065
In this paper, we shall study the parabolic-elliptic Keller--Segel system on the Poincare disk model of the two-dimensional-hyperbolic space. We shall investigate how the negative curvature of this...

Publikováno v: Colloquium Mathematicum
Colloquium Mathematicum, 2014, 137 (2), pp.189-208. ⟨10.4064/cm137-2-4⟩
Several years ago, a French version was available but with a limited diffusion.Here is the final version to appear in Colloquium Mathematicum.(Theorem 4.1 statement (2) corrected); International audience; We prove the equivalence of Nash type and sup

Estimations du Noyau de la Chaleur sur les Espaces Homogènes
Autor: Patrick Maheux
Publikováno v: Journal of Geometric Analysis. 8:65-96
We give upper and lower gaussian estimates for the heat kernel for canonical sub-laplacians on homogeneous spaces of Lie groups. We prove that homogeneous spaces of Lie groups of polynomial growth have the doubling property. We deduce Poincare inequa

Log-Sobolev inequalities for semi-direct product operators and applications
Autor: Patrick Maheux, Piero D'Ancona, Vittoria Pierfelice
Publikováno v: Mathematische Zeitschrift
Mathematische Zeitschrift, Springer, 2016, 283 (1-2), pp.103-131
In this paper, we prove some type of logarithmic Sobolev inequalities (with parameters) for operators in semi-direct product forms (see Sect. 1 for a precise definition). This generalizes the tensorization procedure for this type of inequalities and

Smoothing Methods for Nonlinear Complementarity Problems

Journal of Optimization Theory and Applications, 2014, 160 (3), pp.711-729. ⟨10.1007/s10957-013-0398-1⟩
In this paper, we present a new smoothing approach to solve general nonlinear complementarity problems. Under the $P_0$ condition on the original problems, we prove some existence and convergence results . We also present an error estimate under a ne

Revista Matemática Iberoamericana, European Mathematical Society, 2012, 28 (3), pp.879-906. ⟨10.4171/RMI/695⟩
International audience; Nash or Sobolev inequalities are known to be equivalent to ultracontractive properties of Markov semigroups, hence to uniform bounds on their kernel densities. In this work we present a simple and extremely general method, bas

Nash type inequalities for fractional powers of non-negative self-adjoint operators
Autor: A. Bendikov, Patrick Maheux
Publikováno v: Transaction of the American Mathematical Society.
Transaction of the American Mathematical Society., 2007, 359 (7), pp.3085-3097. ⟨10.1090/S0002-9947-07-04020-2⟩
Assuming that a Nash type inequality is satisfied by a non-negative self-adjoint operator $A$, we prove a Nash type inequality for the fractional powers $A^{\alpha}$ of $A$. Under some assumptions, we give ultracontractivity bounds for the semigroup
