The Picard group of a noncommutative algebraic torus
Journal of Noncommutative Geometry, 2013 Let A_q := \mathbb{C}\langle x^{\pm 1}, y^{\pm 1}\rangle/(xy-qyx) . Assuming that q is not a root of unity, we compute the Picard group

GENERATORS OF THE EISENSTEIN–PICARD MODULAR GROUP [PDF]
Journal of the Australian Mathematical Society, 2011 AbstractWe prove that the Eisenstein–Picard modular group SU(2,1;ℤ[ω3]) can be generated by four given transformations.

Dynamics of Fricke–Painlevé VI Surfaces
DynamicsThe symmetries of a Riemann surface Σ∖{ai} with n punctures ai are encoded in its fundamental group π1(Σ). Further structure may be described through representations (homomorphisms) of π1 over a Lie group G as globalized by the character variety C=Hom(π1,

Communications in Algebra, 2007 We introduce the Picard group of corings. We extend the well-known exact sequence from algebras and coalgebras over fields to corings. We extend the Aut-Pic property to corings and we give some new examples of corings having this property. Finally, we give the corresponding exact sequences for the category of entwined modules over an entwining ...

, 2011 We use our extension of the Noether-Lefschetz theorem to describe generators of the class groups at the local rings of singularities of very general hypersurfaces containing a fixed base locus. We give several applications, including (1) every subgroup of the class group of the completed local ring of a rational double point arises as the class group ...

The Picard groups of the moduli spaces of curves
Topology, 1987 Let \(M_{g,h}\) (\({\mathcal M}_{g,h})\) denote the moduli space (functor) of smooth h-pointed curves of genus \(g\) over \({\mathbb{C}}\), and \(\bar M_{g,h}\) (\(\bar {\mathcal M}_{g,h})\) its natural compactification by means of stable curves. - It is known that the Picard group of \(M_{g,h}\), \(Pic(M_{g,h})\), is a free abelian group on \(h+1 ...

On the v-Picard Group of Stein Spaces
International Mathematics Research NoticesAbstract We study the image of the Hodge–Tate logarithm map (in any cohomological degree), defined by Heuer, in the case of smooth Stein varieties. Heuer, motivated by the computations for the affine space of any dimension, raised the question whether this image is always equal to the group of closed differential forms.
