Exponential-Wrapped Distributions on Symmetric Spaces

چکیده
In many applications, the curvature of space supporting data makes statistical modeling challenging. this paper we discuss construction and use probability distributions wrapped around manifolds using exponential maps. These have already been used on specific manifolds. We describe their in unifying framework affine locally symmetric spaces. Affine spaces are a broad class containing encountered sciences. show that these spaces, exponential-wrapped enjoy interesting properties for practical use. provide generic expression Jacobian appearing compute it two particular examples: Grassmannians pseudohyperboloids. illustrate interest such classification experiment simulated data.

L–distributions on symmetric spaces
The notion of Lp–distributions is introduced on Riemannian symmetric spaces of noncompact type and their main properties are established. We use a geometric description for the topology of the space of test functions in terms of the Laplace–Beltrami operator. The techniques are based on a-priori estimates for elliptic operators. We show that structure theorems, similar to Rn, hold on symmetric ...
متن کاملTruncated-Exponential Skew-Symmetric Distributions
The family of skew distributions introduced by Azzalini and extended by others has received widespread attention. However, it suffers from complicated inference procedures. In this paper, a new family of skew distributions that overcomes the difficulties is introduced. This new family belongs to the exponential family. Many properties of this family are studied, inference procedures developed a...
متن کاملA Paley–wiener Theorem for Distributions on Reductive Symmetric Spaces
Let X = G/H be a reductive symmetric space and K a maximal compact subgroup of G. We study Fourier transforms of compactly supported K-finite distributions on X and characterize the image of the space of such distributions.
متن کاملRotating Black Branes wrapped on Einstein Spaces
We present new rotating black brane solutions which solve Einstein’s equations with cosmological constant Λ in arbitrary dimension d. For negative Λ, the branes naturally appear in AdS supergravity compactifications, and should therefore play some role in the AdS/CFT correspondence. The spacetimes are warped products of a four-dimensional part and an Einstein space of dimension d− 4, which is n...
