Twisted convolution and Riesz means

Journal d'Analyse Mathématique, 1998
Using some estimates of Askey and Wainger for Laguerre functions, the authors improve a result in [\textit{S. Thangavelu}, Ark. Mat. 29, No. 2, 307-321 (1991; Zbl 0765.42009)]. Consider the twisted Laplacian on \(\mathbb{R}^{2n}\), \(n\geq 1\), \[ -\Delta_x- \Delta_y+ 1/4(| x|^2+| y|^2)- i \sum^n_{j=1} \Biggl(x_j{\partial\over\partial y_j}- y_j ...

Semi-Classical Asymptotics of Riesz Means

Journal of the London Mathematical Society, 2000
Summary: The semi-classical asymptotic behaviour of the Riesz means of a distribution of eigenvalues is investigated at a non-critical energy level. For Schrödinger type operators, the second term related to the periodic trajectories of the classical Hamiltonian is obtained.

Riesz Mean-Value Theorem Extended

1983
The mean-value theorem of M. Riesz is valid only for exponents in the range (−1,0]. It is here shown that the theorem can be extended to greater exponents in a modified form by introducing adequate factors which yield a positivity property. Several directions for applications are indicated.

Riesz Means on Graphs and Discrete Groups

Potential Analysis, 2011
For \(\alpha>0\) and \(R>0\), the Riesz mean of order \(\alpha\) is the operator defined by \[ m_{\alpha,R}(\Delta) = \int_0^2 m_{\alpha,R}(\lambda) \mathrm{d}E_\lambda \] where \(\Delta\) is the discrete Laplacian, \(\mathrm{d}E_\lambda\) is its spectral measure (so that \(\Delta = \int_0^2 \lambda \mathrm{d}E_\lambda\)) and \[ m_{\alpha,R}(\lambda) =
