Hermite型算子分数次幂的点态收敛性

Pointwise convergence of fractional powers of Hermite type operators

Guillermo Flores, Gustavo Garrigos, Teresa Signes, Beatriz Viviani

摘要:

当$L$是Hermite算子或Ornstein-Uhlenbeck算子时,我们找到了函数$f$的极小可积性和光滑性条件,使得分数幂$L^σf(x_0)$在给定点$x_0$处定义良好.我们用各种例子说明了条件的最优性。最后,我们对分数阶算子$(-Δ+R)^σ$和$R>0$得到了类似的结果.

英文摘要:

When $L$ is the Hermite or the Ornstein-Uhlenbeck operator, we find minimal integrability and smoothness conditions on a function $f$ so that the fractional power $L^σf(x_0)$ is well-defined at a given point $x_0$. We illustrate the optimality of the conditions with various examples. Finally, we obtain similar results for the fractional operators $(-Δ+R)^σ$, with $R>0$.
