We consider hypoelliptic symbols over a very regular Lie group and discuss monodromy for a spectral stratification using results of Nilsson and Bäcklund.

Pierre Gilles Lemarié-Rieusset

We discuss the Navier-Stokes equations with forces in the mixed norm time-space parabolic Morrey spaces of Krylov.

Gregory Seregin

In the note, the Euler scaling is used to study a certain scenario of potential Type II blowups of solutions to the Navier-Stokes equations.

In the symbol space for differential operators, we discuss a scalar type for change of local coordinates, using vector valued distributions. In particular, we discuss P-convexity for hypoelliptic operators.

Nigeria, with over 200 million people, covers an area of 923,768 km2 and it occupies the eastern section of the West African region (Figure 1). The regions of Nigeria have prehistoric sites spanning from the Early Stone Age through the Middle Stone Age, the Late Stone Age/Neolithic to the Iron Age and the beginning of urbanization. Several historic empires, states and polities developed within the geographical area now occupied by Nigeria and had left archaeological relics.

In the note, a new regularity condition for axisymmetric solutions to the non-stationary 3D Navier-Stokes equations is proven. It is slightly supercritical.

We give an example of a linear, time-dependent, Schr{ö}dinger operator with optimal growth of Sobolev norms. The construction is explicit, and relies on a comprehensive study of the linear Lowest Landau Level equation with a time-dependent potential.

Sobolev trace inequalities on nonhomogeneous fractional Sobolev spaces are established.

We provide a new and simple proof based on Harnack's inequality to the Lipschitz continuity of the solutions of a class of free boundary problems.

A specific class of coagulation and fragmentation coefficients is considered for which the strength of the coagulation is balanced by that of the multiple fragmentation. Existence and uniqueness of mass-conserving solutions are proved when the initial total mass is sufficiently small.

We prove a counterpart of the log-convex density conjecture in the hyperbolic plane.

In this work, we prove the existence of local convex solution to the degenerate Hessian equation

The aim of this article is to identify, document and analyse three participatory actions undertaken in Mexico. They offer an alternative ground for analysis and reflection, as they were conducted outside the control of the State, offering the possibility to use different methodologies that contain key elements to think about a reorganization of the existing relation between Institutions and society. Based on extremely simple principles of action (painting, sweeping and cooking) their effects can help reshape the value and use of archaeological heritage in Mexico.

We prove global well-posedness for the 3D Klein-Gordon equation with a concentrated nonlinearity.

In this paper, we give the asymptotic expansion of $n_{0,d}$ and $n_{1,d}$.
