On fractional Fourier transform moments [PDF]

open access: yesIEEE Signal Processing Letters, 2000
Based on the relation between the ambiguity function represented in a quasi-polar coordinate system and the fractional power spectra, the fractional Fourier transform moments are introduced. Important equalities for the global second-order fractional Fourier transform moments are derived and their applications for signal analysis are discussed.

Hausdorff moment problem and fractional moments

Applied Mathematics and Computation, 2010
In probabilistic terms, the Hausdorff moment problem means to recover an unknown probability density function \(f\in L^2[0,1]\) from the knowledge of its associated sequence \(\{\mu_j\}^M_{j=0}\) of integer moments, that is, \(\mu_j=\int_0^1x^jf(x),j\geq0,\mu_0=1\). The authors propose a solution to the Hausdorff moment problem using fractional moments,

Stieltjes moment problem via fractional moments

Applied Mathematics and Computation, 2005
The authors extend a procedure for the reconstruction of probability density function from the knowledge of its infinite sequence of ordinary moments [cf. the authors, ibid. 144, No. 1, 61--74 (2003; Zbl 1029.44003)] from the case of distributions with finite positive support (Hausdorff case) to the case where the distribution has \([0,\infty ...

On Fractional Moments of Dirichlet L-Functions

Lithuanian Mathematical Journal, 2005
The authors prove the bound \[ c_1(q)T(\log T)^{k^2} \leq \int_0^T| L(1/2+it,\chi)| ^{2k}\,dt \leq c_2(q)T(\log T)^{k^2} \quad(0 < c_1(q) < c_1(q)),\tag{1} \] where \(T\to\infty, k = 1/n, n\in\mathbb N\), \(L(s,\chi)\) is a Dirichlet \(L\)-function with \(\chi(n)\) a character to the modulus \(q\).
