We propose a framework for bilinear multiplier operators defined via the (bivariate) spectral theorem. Under this framework, we prove Coifman-Meyer type multiplier theorems and fractional Leibniz rules. Our theory applies to bilinear multipliers associated with the discrete Laplacian on general bi-radial bilinear Dunkl multipliers, and to bilinear multipliers associated with the Jacobi expansions.
我们提出了一个通过(双变量)谱定理定义的双线性乘子算子框架。在此框架下,我们证明了科伊夫曼 - 迈耶型乘子定理和分数阶莱布尼茨法则。我们的理论适用于与一般双径向双线性邓克尔乘子上的离散拉普拉斯算子相关的双线性乘子,以及与雅可比展开相关的双线性乘子。
