Picard groups and duality for Real Morava $E$-theories [PDF]
, 2018 We show, at the prime 2, that the Picard group of invertible modules over $E_n^{hC_2}$ is cyclic. Here, $E_n$ is the height $n$ Lubin--Tate spectrum and its $C_2$-action is induced from the formal inverse of its associated formal group law.

Picard groups on moduli of K3 surfaces with Mukai models [PDF]
, 2014 We discuss the Picard group of moduli space $\mathcal{K}_g$ of quasi-polarized K3 surfaces of genus $g\leq 12$ and $g\neq 11$. In this range, $\mathcal{K}_g$ is unirational and a general element in $\mathcal{K}_g$ is a complete intersection with respect ...

Journal of Lipid Research, 1998 The effects of CETP gene Taq1B polymorphism on plasma lipoproteins were investigated in 176 patients with non-insulin-dependent diabetes mellitus. The distribution of CETP genotypes was similar to that previously described in the general population.

Picard groups of the moduli spaces of semistable sheaves I [PDF]
, 2004 We compute the Picard group of the moduli space $U'$ of semistable vector bundles of rank $n$ and degree $d$ on an irreducible nodal curve $Y$ and show that $U'$ is locally factorial.

Hecke actions on picard groups
Journal of Pure and Applied Algebra, 1982 The Hecke category \({\mathfrak H}_ G\) of a group \(G\) is defined as the category of the \({\mathbb{Z}}G\)-permutation modules \({\mathbb{Z}}G/H\) for all subgroups \(H\) of \(G\). For any given \({\mathbb{Z}}G\)-module \(M\) one defines in a natural way a contravariant additive functor \(\Phi_ M: {\mathfrak H}_ G\to\) Abelian groups, with \(\Phi_ M({

Picard Groups and Refined Discrete Logarithms [PDF]
LMS Journal of Computation and Mathematics, 2005 AbstractLet K denote a number field, and G a finite abelian group. The ring of algebraic integers in K is denoted in this paper by $/cal{O}_K$, and $/cal{A}$ denotes any $/cal{O}_K$-order in K[G]. The paper describes an algorithm that explicitly computes the Picard group Pic($/cal{A}$), and solves the corresponding (refined) discrete logarithm problem.

Phytoplankton coastal-offshore monitoring by the Strait of Dover at high spatial resolution: the DYPHYRAD surveys [PDF]
Earth System Science DataLong-term monitoring of phytoplankton communities is essential for understanding the functioning and evolution of marine systems. This paper presents a decadal dataset on phytoplankton observations conducted along a coastal-offshore transect by the ...

On the geometry of lattices and finiteness of Picard groups [PDF]
, 2019 Let (K, O, k) be a p-modular system with k algebraically closed and O unramified, and let Λ be an O-order in a separable K-algebra. We call a Λ-lattice L rigid if Ext1Λ(L, L) = 0, in analogy with the definition of rigid modules over a finite-dimensional ...

Colloquium Mathematicum, 1997 This paper is one of three papers of the authors on Picard groups. The other two are ``Picard groups and infinite matrix rings'' (to appear) and ``Outer induced Picard group'' (to appear). By definition the Picard group of a ring \(A\) with local units is the group of category-auto-equivalences of \(A\)-Mod.

Stacks of uniform cyclic covers of curves and their Picard groups [PDF]
, 2015 We study the stack B_{h,g,n} of uniform cyclic covers of degree n between smooth curves of genus h and g and, for h >> g, present it as an open substack of a vector bundle over the universal Jacobian stack of M_g.
