The Riesz Transform and Fractional Integral Operators in the Bessel Setting

Jorge J. Betancor, Xuan Thinh Duong, Ming-Yi Lee +2

Fix $λ > 0$ . Consider the Bessel operator $△_{λ} := - \frac{d ^{2}}{d x ^{2}} - \frac{2 λ}{x} \frac{d}{d x}$ on $R_{+}$ , where $R_{+} := (0, \infty)$ and $d m_{λ} := x^{2 λ} d x$ with $d x$ …

Sharp estimates for imaginary powers of Bessel operators

The Anh Bui, Xuejing Huo, Ji Li

Let $L f (x) := - \frac{d ^{2}}{d x ^{2}} f (x) - \frac{r}{x} \frac{d}{d x} f (x), x > 0, r > 0$ be the Bessel operator on $((0, \infty), ∣ \cdot ∣, x^{r} d x)$ . In this paper, we prove the sharp weak typ…
