Pricing multi-asset options with tempered stable distributions

Financial Innovation
We derive methods for risk-neutral pricing of multi-asset options, when log-returns jointly follow a multivariate tempered stable distribution. These lead to processes that are more realistic than the better known Brownian motion and stable processes ...

Characterization of regular tempered distributions [PDF]

Annales Polonici Mathematici, 1983
This paper gives an elementary proof of the following property: a locally Lebesgue integrable complex valued function u is a regular tempered distribution, i.e., \(u[\sigma]=\int u(x)\sigma (x)dx\) for \(\sigma \in S\) (with \(u\sigma\in L_ 1)\) iff for a certain non-negative integer k the function \(R^ n\ni x\mapsto u(x)/(1+| x|^ 2)^ k\) is integrable

Kinship, Marriage and Traces of Social Interaction - Aspects on the hunter-gatherer societies in northern Sweden during the Bronze Age and early Iron Age

Current Swedish Archaeology, 1996
A central problem in the explanation and description of decentralized hunter-gatherer societies is what kind of traces different sorts of social interaction will leave in the archaeological material.

Tempered distributions: does universal tempering procedure exist?

, 2015
Since the turn of the century, there has been increased interest in the application of heavy-tailed distributions, particularly stable distributions, to problems in physics and finance. Although, the tails of stable distributions provide a better fit to real-world data, they are too fat to describe empirical distributions.

Boundary condition effects on failure of tempered glass subject to wind-borne debris impact and a quantification model for fragment distribution

Baozha yu Chongji
This study addressed critical safety concerns in wind-resistant design of building envelope systems, aiming to quantify secondary fragmentation effects and potential risks from tempered glass breakage under wind-borne debris impact.

A Note on Directional Wavelet Transform: Distributional Boundary Values and Analytic Wavefront Sets

International Journal of Mathematics and Mathematical Sciences, 2012
By using a particular class of directional wavelets (namely, the conical wavelets, which are wavelets strictly supported in a proper convex cone in the k-space of frequencies), in this paper, it is shown that a tempered distribution is obtained as a ...

Mehler Kernel Approach to Tempered Distributions

Tokyo Journal of Mathematics, 2006
The main purpose of the paper is to establish the characterization of the Hermite heat equation \((\partial_t-\triangle+| x| ^2)U(x,t)=0\) satisfying a growth restriction in terms of distributions on the Mehler kernel. \textit{R. S. Strichartz}' Theorem 3.2 from [Trans. Am. Math. Soc. 338, 971--979 (1993; Zbl 0815.35012)] is generalized.
