Integration of U‐Pb, Hf isotope and trace element analyses of detrital zircon and rutile decipher provenance. Potential source areas of broadly coeval formation are discriminated by multi‐proxy analysis. Integrated analysis of the detrital record after major geodynamic changes captures sedimentary reorganization.

Abstract The construction of ocean island basaltic volcanoes consists of a succession of eruptions, intrusions, and metamorphism. These events are often temporally ill‐constrained because the most widely used radiometric dating methods applicable to mafic volcanic rocks (K‐Ar or 40Ar/39Ar on whole rock or groundmass) are prone to inaccuracy when ...

Sharp estimates for W-invariant Dunkl and heat kernels in the A case
In this article, we prove exact estimates for the $W$-invariant Dunkl kernel and heat kernel, for the root system of type $A$ with arbitrary positive multiplicities. We apply the estimates of the $W$-invariant Dunkl heat kernel to compute sharp estimates for the Newton kernel and for the $s$-stable semigroups generated by a fractional power of the $W ...

Upper and lower bounds for Dunkl heat kernel
On $\mathbb R^N$ equipped with a normalized root system $R$, a multiplicity function $k(α) > 0$, and the associated measure $$ dw(\mathbf x)=\prod_{α\in R}|\langle \mathbf x,α\rangle|^{k(α)}\, d\mathbf x, $$ let $h_t(\mathbf x,\mathbf y)$ denote the heat kernel of the semigroup generated by the Dunkl Laplace operator $Δ_k$.

On the estimates of the Dunkl Kernel
In this paper, we are interested in the estimates of the Dunkl Kernel on some special sets, following the work of M.F.E. de Jeu and M. Rösler in \cite{R3}.

Generalized Bessel function of Type D [PDF]
We write down the generalized Bessel function associated with the root system of type $D$ by means of multivariate hypergeometric series. Our hint comes from the particular case of the Brownian motion in the Weyl chamber of type $D$.Comment: This is a ...

Generalized Hermite Polynomials and the Heat Equation for Dunkl Operators
Based on the theory of Dunkl operators, this paper presents a general concept of multivariable Hermite polynomials and Hermite functions which are associated with finite reflection groups on $\b R^N$.
