We define generalized Clifford parallelisms in PG(3, F ) with the help of a quaternion skew field H over arbitrary characteristic.Moreover we give geometric description such involving hyperbolic quadrics projective spaces suitable quadratic extensions .
Here we present both an algebraic and a geometric representation of the limit rotation loop build in [7], interpret its main properties these settings determine automorphism group.
Given two parallelisms of a projective space we describe construction, called blending, that yields (possibly new) parallelism this space. For double $$({\mathbb P},{\mathrel {\parallel _{\ell }}},{\mathrel _{r}}})$$ over quaternion skew field characterise the “Clifford-like” parallelisms, i.e. blends Clifford $$\mathrel }}$$ and _{r}}$$ , in geometric an algebraic way. Finally, establish necessary sufficient conditions for existence Clifford-like are not Clifford.
Abstract Here we study the relationship between stability of coherent systems and holomorphic triples over a curve arbitrary genus. Moreover apply these results to some properties give examples on projective line.
Given two parallelisms of a projective space we describe construction, called blending, that yields (possibly new) parallelism this space. For double $(\mathbb{P},\parallel_\ell,\parallel_r)$ over quaternion skew field characterise the "Clifford-like" parallelisms, i.e. blends Clifford $\parallel_\ell$ and $\parallel_r$, in geometric an algebraic way. Finally, establish necessary sufficient conditions for existence Clifford-like are not Clifford.
Abstract We recall the notions of Clifford and Clifford-like parallelisms in a 3-dimensional projective double space. In previous paper authors proved that linear part full automorphism group parallelism is same for all which can be associated to it. this paper, instead, we study action such on parallel classes thus achieving our main results characterisation among ones.
En Here we study affine parallel translation structures, both finite and infinite, with a principal line, that is line which intersects every not in its class. These structures can be regarded also as (finite or infinite) transversal divisible designs. An algebraic characterization of these terms semidirect product groups provided the main properties related to their group automorphisms are inspected. The particular case kinematic spaces taken into consideration.
We recall the notions of Clifford and Clifford-like parallelisms in a $3$-dimensional projective double space. In previous paper authors proved that linear part full automorphism group parallelism is same for all which can be associated to it. this paper, instead, we study action such on parallel classes thus achieving our main results characterisation among ones.
In this paper we focus on the description of automorphism group $\Gamma_{\parallel}$ a Clifford-like parallelism $\parallel$ $3$-dimensional projective double space $\bigl(\mathbb{P}(H_F),{\mathrel{\parallel_{\ell}}},{\mathrel{\parallel_{r}}}\bigr)$ over quaternion skew field $H$ (with centre $F$ any characteristic). We compare with $\Gamma_{\ell}$ left $\mathrel{\parallel_{\ell}}$, which is strictly related to $\mathrm{Aut}(H)$. build up and discuss several examples showing that certain...
Abstract We focus on the description of automorphism group Γ ∥ a Clifford-like parallelism 3-dimensional projective double space (ℙ( H F ), ℓ , r ) over quaternion skew field (of any characteristic). compare with left which is strictly related to Aut( ). build up and discuss several examples showing that certain fields it possible choose in such way either properly contained or coincides even though ≠ .
Abstract Here we study the α-stability for holomorphic triples on bielliptic curves. In particular some existence theorems α-stable are proved using as main tool of elliptic Elementary transformations also taken into consideration.
