-Estimates for maximal averages along mixed homogeneous hypersurfaces in

Stefan Buschenhenke, Wenjuan Li, Detlef Müller +1

In this paper, we study -estimates for maximal averaging operators along hypersurfaces in which are the graph of a mixed homogeneous function…

-estimates for FIO-cone multipliers

Stefan Buschenhenke, Spyridon Dendrinos, Isroil A. Ikromov +1

The classical cone multipliers are Fourier multiplier operators which localize to narrow -neighborhoods of the truncated light cone in frequency space. By composing such convo…

Estimates for maximal functions associated to hypersurfaces in with height Part II -- A geometric conjecture and its proof for generic 2-surfaces

Stefan Buschenhenke, Isroil A. Ikromov, Detlef Müller

In this article, we continue the study of -boundedness of the maximal operator associated to averages along isotropic dilates of a given, smooth hypersurface $S…

Factorisation in Restriction theory and near extremisers

Stefan Buschenhenke

We give an alternative argument to the application of the so-called Maurey- Nikishin-Pisier factorisation in Fourier restriction theory. Based on an induction-on-scales argument, o…

Fourier restriction for smooth hyperbolic 2-surfaces

Stefan Buschenhenke, Detlef Müller, Ana Vargas

We prove Fourier restriction estimates by means of the polynomial partitioning method for compact subsets of any sufficiently smooth hyperbolic hypersurface in threedimensional euc…

A Fourier restriction theorem for a perturbed hyperbolic paraboloid: polynomial partitioning

Stefan Buschenhenke, Detlef Müller, Ana Vargas

We consider a surface with negative curvature in which is a cubic perturbation of the saddle. For this surface, we prove a new restriction theorem, analogous to the theo…

Partitions of flat one-variate functions and a Fourier restriction theorem for related perturbations of the hyperbolic paraboloid

Stefan Buschenhenke, Detlef Müller, Ana Vargas

We continue our research on Fourier restriction for hyperbolic surfaces, by studying local perturbations of the hyperbolic paraboloid which are of the form wher…

On Fourier restriction for finite-type perturbations of the hyperboloid

Stefan Buschenhenke, Detlef Müller, Ana Vargas

In this note, we continue our research on Fourier restriction for hyperbolic surfaces, by studying local perturbations of the hyperbolic paraboloid which are of the form $z…

On the nonlinear Brascamp-Lieb inequality

Jonathan Bennett, Neal Bez, Stefan Buschenhenke +2

We prove a nonlinear variant of the general Brascamp-Lieb inequality. Instances of this inequality are quite prevalent in analysis, and we illustrate this with substantial applicat…

A Fourier restriction theorem for a perturbed hyperbolic paraboloid

Stefan Buschenhenke, Detlef Müller, Ana Vargas

In contrast to elliptic surfaces, the Fourier restriction problem for hypersurfaces of non-vanishing Gaussian curvature which admit principal curvatures of opposite signs is still…

The nonlinear Brascamp-Lieb inequality for simple data

Jonathan Bennett, Neal Bez, Stefan Buschenhenke +1

We establish a nonlinear generalisation of the classical Brascamp-Lieb inequality in the case where the Lebesgue exponents lie in the interior of the finiteness polytope. As a coro…

Estimates for maximal functions associated to hypersurfaces in with height Part I

S. Buschenhenke, S. Dendrinos, I. A. Ikromov +1

In this article, we continue the study of the problem of -boundedness of the maximal operator associated to averages along isotropic dilates of a given, smooth hypersurfac…

A Fourier Restriction Theorem For A Twodimensional Surface Of Finite Type

Stefan Buschenhenke, Detlef Müller, Ana Vargas

The problem of Fourier restriction estimates for smooth hypersurfaces S of finite type in R^3 is by now very well understood for a large class of hypersurfaces…

A sharp Lp Lq Fourier restriction theorem for a conical surface of finite type

Stefan Buschenhenke

We present a restriction theorem for the Fourier transform to a 2-dimensional conical surface of finite type, obtaining a sharp result, which improves previous work by Barcelo.
