Abstract

In this article, we study a weighted analogue of the totally geodesic $k$-plane transform on the real hyperbolic space. Throughout the article, we are concerned with the mapping properties of this transform. Particularly, we first consider the existence of the operator on weighted Lebesgue spaces, where the weights under consideration are natural to the geometry of the hyperbolic space. Then, we proceed to see the $L^p$-improving mapping properties of the said transform on radial functions. Further, we also prove end-point boundedness results on Lorentz spaces of radial functions. Lastly, we look into the problem of weighted $L^p$-$L^p$ boundedness, and obtain partial results in this direction. In the way of obtaining these results, we also give a spherical integral representation of the weighted totally geodesic $k$-plane transform.

Hausdorff dimension of the graph of a random vector-valued Weierstrass function

Let $\{θ_n,λ_n:n\geq0\}$ be mutually independent random variables, each uniformly distributed on $[0,1]$, and write $Θ=(θ_n)_{n\geq0}$ and $Λ=(λ_n)_{n\geq0}$. The random vector-valued Weierstrass function is given by $$f_{Θ,Λ}(x)= \left( \sum_{n=0}^{\infty} a^n\cos\bigl(2π(b^n x+θ_n)\bigr),\ \sum_{n=0}^{\infty} a^n\sin\bigl(2π(b^n x+λ_n)\bigr) \right), \; x\in[0,1],$$ where $0 1$. The Hausdorff dimension of the graph of this function is proved to be $$\dim_H G(f_{Θ,Λ}) = \min\left\{-\frac{\log b}{\log a}, \, 3 +2\frac{\log a}{\log b}\right\} \quad \text{a.s}.$$

Characterization of the boundedness of the segment multiplier on rearrangement-invariant spaces

Given rearrangement-invariant (r.i.) spaces $X$ and $Y$, we show that the segment multiplier, the truncated Hilbert transform, and the discrete Hilbert transform (on the associated discretized space) are bounded from $X$ to $Y$ simultaneously. Moreover, when $X = Y$ this boundedness is characterized by a condition on a pair of Boyd-type indices. We also exhibit an r.i. space on which the segment multiplier is bounded while the (non-truncated) Hilbert transform fails to be bounded.

Endpoint regularity of Radon transforms associated with real analytic phases in the plane

In this paper, we consider the endpoint Sobolev regularity of Radon transforms associated with real-analytic functions in the plane. We establish all of the failure of endpoint regularity for real-analytic phases. On the one hand, the critical endpoint regularity $L^p(\mathbb{R}^2)\rightarrow L^p_s(\mathbb{R}^2)$, corresponding to extreme points of the reduced Newton polyhedron of phase function, is true if only and only if $p=2$. For generic extreme points, this failure of endpoint regularity generalizes a result of Christ \cite{christ}. On the other hand, we find that the endpoint Sobolev regularity also fails on a bounded segment of the reduced Newton polyhedron when the bisectrix $y=x$ intersects one of unbounded faces at a relative interior point. In particular, our results imply that the Radon transform is not bounded from $L^p$ into $L^p_{1/n}$ with $p=n/(n-1)$ or $p=n$, where the phase functions are real-valued homogeneous polynomials $S(x,y)=a_1x^{n-1}y+a_2x^{n-2}y^2+\cdots+a_{n-1}xy^{n-1}$ with $n\geq 3$ and $a_1a_{n-1}\neq0$. This answers a problem of Phong and Stein in 1994. Moreover, the main results of this paper also give examples which show failure of critical Sobolev regularity for degenerate Fourier integral operators satisfying finite type conditions formulated in \cite{Seeger93,seeger2}. Based on earlier results and our proof of several remaining cases, we conclude that all of other critical endpoint Sobolev estimates are true for Radon transforms associated with real-analytic phases in the plane. Therefore, all failures of endpoint regularity estimates are clearly determined.
