Insight into the optimal control strategies on corruption dynamics using fractional order derivatives

Scientific African
The fractional-order design for conceptualizing corruption offers several advantages on the corruption spreading over the integer-order corruption models such as acknowledgement of the intricate dynamics of corruption, including corruption super ...

Jørgensen subgroups of the Picard group

Osaka Journal of Mathematics, 2007
Let $G$ be a subgroup of rank two of the Möbius group $\textit{PSL}(2, \mathbb{C})$. The Jørgensen number $J(G)$ of $G$ is defined by \[ J(G) = \inf \{|\tr^{2} A - 4| + \mathopen|\tr[A, B]-2|\colon \langle A, B\rangle= G\}. \] We describ e all subgroups $G$ of the Picard group $\textit{PSL}(2, \mathbb{Z} + i\mathbb{Z})$ with $J(G) = 1$.

Picard group

, 1996
Bu çalışmada PSL(2, C) grubunun bir alt grubu olan Picard grubu ve bunun bazı alt grupları ele alınmıştır. Bu grup ilk olarak Picard tarafından incelenmiştir. Daha sonra Fricke ve Klein tarafından Picard grubu olarak adlandırılmıştır.

The Picard Group of Corings

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 ...

The Picard Group of Equivariant Stable Homotopy Theory [PDF]

, 2001
Let G be a compact Lie group. We describe the Picard group Pic(HoGS) of invertible objects in the stable homotopy category of G-spectra in terms of a suitable class of homotopy representations of G.

Combinatorial aspects of nodal curves

Le Matematiche, 2006
To any nodal curve C one associates its degree class group, a combinatorial invariant which plays an important role in the compactification of the generalized Jacobian of C and in the construction of the Néron model of the Picard variety of families of ...

Differential Galois Theory and Hopf Algebras for Lie Pseudogroups

Axioms
According to a clever but rarely quoted or acknowledged work of E. Vessiot that won the prize of the Académie des Sciences in 1904, “Differential Galois Theory” (DGT) has mainly to do with the study of “Principal Homogeneous Spaces” (PHSs) for finite ...

Extending divisors from complete intersection surfaces

Le Matematiche, 2007
The aim of this paper is to extend a theorem of Griffiths, Harris and Hulek [4], [6] on the extendability of divisors of a smooth complete intersection surface in P^n to the case when the ambient space is a product of projective spaces or a Grassmannian.

On the v-Picard Group of Stein Spaces

International Mathematics Research Notices
Abstract 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.
