Drinfeld module - Wikipedia
In mathematics, a Drinfeld module (or elliptic module) is roughly a special kind of module over a ring of functions on a curve over a finite field, generalizing
A review of elliptical and disc galaxy structure, and modern scaling laws
A century ago, in 1911 and 1913, Plummer and then Reynolds introduced their models to describe the radial distribution of stars in `nebulae'. This article reviews the progress since then, providing both an historical perspective and a contemporary re...
Evolution in the Color-Magnitude Relation of Early-Type Galaxies in Clusters of…
We present a study of the color evolution of elliptical and S0 galaxies in six clusters of galaxies inside the redshift range 0.78 < z < 1.27. For each cluster, we used imaging from the Hubble Space Telescope to determine morphological types by bot...
G4-Flux and Standard Model Vacua in F-theory
We study the geometry of gauge fluxes in four-dimensional F-theory vacua with gauge group SU(3)xSU(2)xU(1)xU(1) and its implications for phenomenology. The models are defined by a previously introduced class of elliptic fibrations whose fibre is give...
Charge asymmetry dependence of anisotropic flow in pPb and PbPb collisions with…
In nucleus-nucleus collisions, the linear dependence found for the elliptic flow harmonic of both positive or negative charged particles as a function of event charge asymmetry is predicted by the phenomenon known as the Chiral Magnetic Wave (CMW) du...
Double-orientations on supersingular isogeny graphs
We recall and define various kinds of supersingular $\ell$-isogeny graphs and precise graph isomorphism with a corresponding quaternion $\ell$-ideal graph. In particular, we introduce the notion of double-orientations on supersingular elliptic curves...
A two-phase model of galaxy formation: II. The size-mass relation of dynamically…
In Paper-I we developed a two-phase model to connect dynamically hot galaxies (such as ellipticals and bulges) with the formation of self-gravitating gas clouds (SGCs) associated with the fast assembly of dark matter halos. Here we explore the implic...
Criptografia com Curvas Elípticas
This paper presents an overview of the use of elliptic curves in cryptography. The security of this cryptosystem is based on the discrete logarithm problem, which appears to be much harder compared to the discrete logarithm problem in other cryptosys...
Photometry and Spectroscopy of Coma Dwarf Ellipticals
We have used deep R- and B-band CCD images (with ~1.2 arcsec seeing) of the central ~700 arcmin^2 of the Coma cluster core (and an associated ~270 arcmin^2 control field) to study the early-type dwarf elliptical (dE) galaxy population. Analysis of...
The Chandra Fornax Survey - I: The Cluster Environment
We present the first results of a deep Chandra survey of the inner 1 degree of the Fornax cluster of galaxies. Ten 50 ksec pointings were obtained in a mosaic centered on the giant elliptical galaxy NGC 1399 at the nominal cluster center. Emission...
A study on iterative methods for solving Richards` equation
This work concerns linearization methods for efficiently solving the Richards` equation,a degenerate elliptic-parabolic equation which models flow in saturated/unsaturated porous media.The discretization of Richards` equation is based on backward Eul...
ZYAM and $\bf v_2$: Underestimating jet yields from dihadron azimuth correlation…
Dihadron azimuth correlations can provide combinatoric access to jet structure in nuclear collisions. To isolate true jet yields a background must be subtracted, including a constant offset and a contribution from "elliptic flow" (azimuth quadrupol...
Note on the Distribution of the Traces of Frobenius
Let $E$ be a nonsingular elliptic curve over the rational numbers, and let $τ^n=p^n+1-\#E(\mathbb{F}_{p^n})$. A result in the current literature claims that the normalized traces of Frobenius $α_n=(τ^n+\overlineτ^n)/2p^{n/2}$ are equidistributed...
Twists of elliptic curves - Wikipedia

Metrology and Time
The algorithm Pi/sinx reveals an elliptic excess which acts as the real component (Space) inducing the imaginary component (Time). Key words : metrology, chronogenesis, tropic year, anomalistic year. ----- L 'algorithme Pi/sinx revele un excede...
Using the Immersed Penalized Boundary Method with Splines to Solve PDE's on Curv…
Second-order elliptic boundary-value problems defined on curved domains in 2D and 3D arise frequently in practice. A lot of work has gone into developing numerical methods for solving such problems. One of the newest and most promising methods is the...
Boundary motive, relative motives and extensions of motives
We explain the role of the boundary motive in the construction of certain Chow motives, and of extensions of Chow motives. Our two main examples concern proper, singular surfaces and fibre products of a universal elliptic curve....
Local theta correspondence and the lifting of Duke, Imamoglu and Ikeda
We use results on the local theta correspondence to prove that for large degrees the Duke-Imamoglu-Ikeda lifting of an elliptic modular form is not a linear combination of theta series....
Mayall II = G1 in M31: Giant Globular Cluster or Core of a Dwarf Elliptical Gala…
(Abridged version) Mayall II = G1 is one of the brightest globular clusters belonging to M31, the Andromeda galaxy. Our observations with HST/WFPC2 provide data for the (I vs. V-I) and (V vs. V-I) color-magnitude diagrams. From model fitting, we de...
