Weak and strong types estimates for square functions associated with operators

Mingming Cao, Zengyan Si, Juan Zhang

Let $L$ be a linear operator in $L^{2} (R^{n})$ which generates a semigroup $e^{- t L}$ whose kernels $p_{t} (x, y)$ satisfy the Gaussian upper bound. In this paper, we investigate s…

Almost everywhere divergence of spherical harmonic expansions and equivalence of summation methods

Xianghong Chen, Dashan Fan, Juan Zhang

We show that there exists an integrable function on the $n$ -sphere $(n \geq 2)$ , whose Cesàro (C, $\frac{n - 1}{2}$ ) means with respect to the spherical harmonic expansion diverge unbou…
