Let ${\widetilde {\mathcal O}}(\mathbf B)$ be the category of (open) subcategories of a topological groupoid ${\mathbf B}.$ This paper concerns with the ${\mathbf {Cat}}$-valued sheaves over category ${\widetilde {\mathcal O}}(\mathbf B).$ Since ${\mathbf {Cat}}$ is not a concrete category, traditional definition of pr... | Seja ${\widetilde {\mathcal O}}(\mathbf B)$ a categoria das subcategorias (abertas) de um grupóide topológico ${\mathbf B}.$ Este artigo trata dos feixes com valores em ${\mathbf {Cat}}$ sobre a categoria ${\widetilde {\mathcal O}}(\mathbf B).$ Como ${\mathbf {Cat}}$ não é uma categoria concreta, a definição tradiciona... | pt |
Foreseeing the era of high spatial resolution measurements of the Sunyaev-Zel'dovich effect (SZE) in clusters of galaxies, we present a prototype analysis of this sort combined with Chandra X-ray data. It is applied specifically to RX J1347-1145 at z=0.451, the most X-ray-luminous galaxy cluster known, for which the hi... | Meramalkan era pengukuran kesan Sunyaev-Zel'dovich (SZE) resolusi ruang tinggi dalam gugusan galaksi, kami mempersembahkan analisis prototaip yang digabungkan dengan data sinar-X Chandra.

We discuss stochastic calculus for large classes of Gaussian processes, based on rough path analysis. Our key condition is a covariance measure structure combined with a classical criterion due to Jain and Monrad [Ann. Probab. 11 (1983) 46-57]. This condition is verified in many examples, even in absence of explicit ex... | 거칠한 경로 해석을 기반으로 하는 광범위한 가우스 과정들의 확률적 미적분학을 논의한다. 우리의 핵심 조건은 재인과 몬라드(Jain and Monrad)[Ann.

We wish to use graded structures [KrVu87], [Vu01] on dffierential operators and quasimodular forms on classical groups and show that these structures provide a tool to construct p-adic measures and p-adic L-functions on the corresponding non-archimedean weight spaces.

Permutation entropy techniques can be useful in identifying anomalies in paleoclimate data records, including noise, outliers, and post-processing issues. We demonstrate this using weighted and unweighted permutation entropy of water-isotope records in a deep polar ice core.
