Abstract

This paper investigates a necessary and sufficient condition for a measurable function on $\mathbb{R}^{\times} \times \mathbb{R}^{d}$ to be the continuous wavelet transform of a complex Radon measure on $\mathbb{R}^{d}$ under suitable regularity conditions on the wavelets. We define a new norm on the collection of such functions and show that it is isometrically isomorphic to the Banach algebra of complex Radon measures under convolution. We show a wavelet inversion formula for measures, in a restricted sense. Under additional hypothesis, we provide a reconstruction formula for the measure of closed rectangles in $\mathbb{R}^d$ using wavelet transforms. We have included supporting examples to substantiate these assumptions.

A Sharp Planar Fractional Isoperimetric Inequality

In this article, we prove the sharp form of the fractional isoperimetric inequality in the plane, originally posed by Maz'ya [Problem 1, Integral Equations Operator Theory, 2018]. More precisely, we show that, for any given $s\in(0,1)$ and any bounded domain $Ω\subset \mathbb{R}^2$ with $C^1$ boundary, $$ P_s(Ω) \le \frac{π^{s-\frac{1}{2}}Γ\left(\frac{3-s}{2}\right)}{s(1-s)Γ\left(\frac{4-s}{2}\right)}\left[\mathcal{H}^1(\partialΩ)\right]^{2-s}, $$ where $P_s$ denotes the fractional $s$-perimeter, $Γ$ denotes the Gamma function, and $\mathcal{H}^{1}$ denotes the $1$-dimensional Hausdorff measure on $\mathbb{R}^2$. The constant is sharp and equality is attained by the disk. The proof proceeds in three steps: reducing the fractional perimeter to a chord functional, reducing connected domains to convex bodies, and proving the sharp convex chord inequality via a fractional Willmore-type inequality, a variational formula along outer parallel bodies, and asymptotic analysis.

Norms of the Hilbert Matrix Operator on Some Analytic Function Spaces

For $\mathcal H:\mathcal B^α\to\mathcal B^α$ with $1<α<2$, we obtain an exact norm representation. In particular, the norm is given by an explicit Gamma-function formula for $1<α\leq3/2$, whereas for $3/2<α<2$ it strictly exceeds the corresponding Gamma-function expression. For $\mathcal H:\mathcal B^α\to\mathcal B^α_{\log}$, we determine the exact norm: it is equal to $3/2$ for $1<α\leq4/3$ and is given by an explicit Gamma-function formula for $4/3<α<2$. We also determine the exact norm of $\mathcal H:H^1\to H^1_{\log}$ and show that it is equal to $π$. Finally, for $0<α<1$, we determine the exact norm of $\mathcal H:H^\infty_α\to\mathcal B^{α+1}$, which is given by an explicit Gamma-function formula.

Second quantization and compactness of induced Gaussian quantum Markov semigroups

We characterize compactness of the Hilbert-Schmidt semigroups induced by finite-mode Gaussian quantum Markov semigroups with a faithful normal invariant state. A unitary second-quantization representation for every $ s $-embedding shows that compactness at one positive time, compact resolvent, drift stability, and uniqueness of the normal invariant state are equivalent. These conditions imply immediate trace-class membership for all embeddings. We derive exact trace-norm and Hilbert-Schmidt norm formulas, an embedding-independent trace identity, and the generator spectrum with algebraic multiplicities. Examples show that compactness does not require the existence of a spectral gap and that a spectral gap need not imply compactness when the invariant state is not unique.
