Root, flow and order polytopes with connections to toric geometry
Forum of Mathematics, SigmaIn this paper, we study the class of polytopes which can be obtained by taking the convex hull of some subset of the points $\{e_i-e_j \ \vert \ i \neq j\} \cup \{\pm e_i\}$ in $\mathbb {R}^n$ , where $e_1,\dots ,e_n$ is the standard ...

Optical-reconstructive treatment of a patient with essential-mesodermal dystrophy of the iris
Офтальмохирургия, 2020 Essentially mesodermal dystrophy of the iris is a type of iridocorneal endothelial syndrome and has a chronic progressive course. It stems from the local fibrosis in the outer border of the iris, which subsequently leads the peripheral iris to pull up ...

School Board Elections in England and Wales, 1870–1902: An Electoral Experiment?
History, EarlyView.Abstract The 1870 Elementary Education Act enabled the creation of school boards in England and Wales. Members were directly elected by the cumulative vote. This method gave each individual voter as many votes as there were seats on a school board, in some cases up to fifteen.

Toric schemes over a discrete valuation ring and tropical compactifications [PDF]
, 2009 textLet Y be a subvariety of an algebraic torus, Tevelv (24) defined and studied tropical compactifications as certain nice compactifications of Y. We give a criterion for certain compactification to be a schön compactification, and as a corollary, we ...

Journal of High Energy Physics, 2020 We study the action growth rate in the Wheeler-DeWitt (WDW) patch for a variety of D ≥ 4 black holes in Einstein gravity that are asymptotic to the anti-de Sitter spacetime, with spherical, toric and hyperbolic horizons, corresponding to the topological ...

Journal for Eighteenth-Century Studies, EarlyView.Abstract The final Stuart monarch, Queen Anne, has often been overlooked in studies of visual and material culture, particularly of fashion and dress. This article is the first to undertake a qualitative and quantitative analysis of the wardrobe accounts of Queen Anne, situating her consumption within the context of the eighteenth‐century fashion ...

Analytic Philosophy, EarlyView.ABSTRACT I defend the non‐instrumentalist thesis that every adult member of a political society has a pro tanto fundamental moral right to an equal democratic say in determining the content of the laws to which she is subject. I begin by giving an account of an important kind of servility that has received only glancing notice in philosophical ...

Biadjoint scalar tree amplitudes and intersecting dual associahedra
Journal of High Energy Physics, 2018 We present a new formula for the biadjoint scalar tree amplitudes m(α|β) based on the combinatorics of dual associahedra. Our construction makes essential use of the cones in ‘kinematic space’ introduced by Arkani-Hamed, Bai, He, and Yan.

Rational points on even‐dimensional Fermat cubics
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract We show that even‐dimensional Fermat cubic hypersurfaces are rational over any field of characteristic not equal to three, by constructing explicit rational parameterizations with polynomials of low degree. As a byproduct of our rationality constructions, we obtain estimates for the number of their rational points over a number field and ...

Secant varieties of toric varieties
Journal of Pure and Applied Algebra, 2007 v1, AMS LaTex, 5 figures, 25 pages; v2, reference added; v3, This is a major rewrite. We have strengthened our main results to include a classification of smooth lattice polytopes P such that Sec X_P does not have the expected dimension. (See Theorems 1.4 and 1.5.) There was also a considerable amount of reorganization, and some expository material was
