Proto-exact categories of matroids, Hall algebras, and K-theory [PDF]

, 2018
This paper examines the category $\mathbf{Mat}_{\bullet}$ of pointed matroids and strong maps from the point of view of Hall algebras. We show that $\mathbf{Mat}_{\bullet}$ has the structure of a finitary proto-exact category - a non-additive ...

Noise-induced macroscopic bifurcations in globally-coupled chaotic units [PDF]

, 2004
Large populations of globally-coupled identical maps subjected to independent additive noise are shown to undergo qualitative changes as the features of the stochastic process are varied.

Preserving a Comprehensive Vegetation Knowledge Base--An Evaluation of Four Historical Soviet Vegetation Maps of the Western Pamirs (Tajikistan). [PDF]

PLoS ONE, 2016
We edited, redrew, and evaluated four unpublished historical vegetation maps of the Western Pamirs (Tajikistan) by the Soviet geobotanist Okmir E. Agakhanjanz. These maps cover an area of 5,188 km2 and date from 1958 to 1960.

Calabi–Yau structures on (quasi-)bisymplectic algebras

Forum of Mathematics, Sigma, 2023
We show that relative Calabi–Yau structures on noncommutative moment maps give rise to (quasi-)bisymplectic structures, as introduced by Crawley-Boevey–Etingof–Ginzburg (in the additive case) and Van den Bergh (in the multiplicative case). We prove along

An Additive Basis for the Chow Ring of \bar{M}_{0,2}(P^r,2) [PDF]

, 2007
We begin a study of the intersection theory of the moduli spaces of degree two stable maps from two-pointed rational curves to arbitrary-dimensional projective space.

Superstability of $m$-additive maps on complete non--Archimedean spaces [PDF]

Sahand Communications in Mathematical Analysis, 2015
The stability problem of the functional equation was conjectured by Ulam and was solved by Hyers in the case of additive mapping. Baker et al. investigated the superstability of the functional equation from a vector space to real numbers.In this paper ...

Cluster synchronization of starlike networks with normalized Laplacian coupling: master stability function approach

, 2015
A generalized model of starlike network is suggested that takes into account non-additive coupling and nonlinear transformation of coupling variables. For this model a method of analysis of synchronized cluster stability is developed.

Measurements of Sub-degree B-mode Polarization in the Cosmic Microwave Background from 100 Square Degrees of SPTpol Data [PDF]

, 2015
We present a measurement of the $B$-mode polarization power spectrum (the $BB$ spectrum) from 100 $\mathrm{deg}^2$ of sky observed with SPTpol, a polarization-sensitive receiver currently installed on the South Pole Telescope.

Symmetric Reverse n-Derivations on Ideals of Semiprime Rings

Axioms
This paper focuses on examining a new type of n-additive map called the symmetric reverse n-derivation. As implied by its name, it combines the ideas of n-additive maps and reverse derivations, with a 1-reverse derivation being the ordinary reverse ...

A multiresolution framework for local similarity based image denoising [PDF]

, 2012
In this paper, we present a generic framework for denoising of images corrupted with additive white Gaussian noise based on the idea of regional similarity.
