We prove that, for every r ≥ 2, the moduli space M X (r; c1, c2) of rank r stable vector bundles with Chern classes c1 = rH and c2 = 1 2 (3r 2 − r) on a nonsingular cubic surface X ⊂ P3 contains a nonempty smooth open subset formed by ACM bundles, i.e. vector bundles with no intermediate cohomology. The bundles we consider for this study are extremal for the number of generators of the correspo...

introduction: in the absence of microvascular replantation or in crash injury cases in which obtaining an acceptable function is not possible, amputation of the injured finger seems to be the best treatment modality. some studies recommended leech therapy for this kind of injury after vascular repair to decrease venous congestion. case presentation: in this case report, the authors presented a ...

Iterated Grassmannian bundles over moduli stacks of vector bundles on a curve are shown to be birational to an affine space times a moduli stack of degree 0 vector bundles, following the method of King and Schofield. Applications include the birational type of some Brill-Noether loci, of moduli schemes for vector bundles with parabolic structure or with level structure and for A. Schmitt’s deco...

Abstract Because of its regularity, it is relatively easy to learn read and spell in Finnish. However, a specific hurdle spelling acquisition seems be the doubling consonant letters. In this study on letter Finnish children (91 Grade 1 191 2 children), we asked two questions. First, are items with double letters (e.g., “kissa” [ˈkisːɑ] ‘cat’) indeed harder than single “kisa” [ˈkisɑ] ‘contest’)?...

A stratified bundle is a fibered space in which strata are classical bundles and in which attachment of strata is controlled by a structure category F of fibers. Well known results on fibre bundles are shown to be true for stratified bundles; namely the pull back theorem, the bundle theorem and the principal bundle theorem. AMS SC : 55R55 (Fiberings with singularities); 55R65 (Generalizations o...

Let G be a split connected reductive algebraic group. E ? B $\mathcal {E}\longrightarrow \mathcal {B}$ × $G\times G$ -torsor over smooth base scheme and X regular compactification of G. We describe the Grothendieck ring associated fibre bundle ( ) : = {E}(X):=\mathcal {E}\times _{G\times G} X$ , as an algebra canonical toric flag . These are relative versions corresponding results on in case wh...

conclusions full echocardiographic examination of the right ventricle, including rvot is essential for the diagnosis of this disease. surgical correction appears to be a successful strategy for management of this rare condition in adults. case presentation we report a 40-year-old man who was referred to cardiology clinic for work-up of dyspnea and a heart murmur found on his physical examinatio...

We develop the theory of smooth principal bundles for a group G, using framework diffeological spaces. After giving new examples showing why arbitrary cannot be classified, we define D-numerable bundles, analogs numerable from topology, and prove that pulling back bundle along smoothly homotopic maps gives isomorphic pullbacks. then structures on Milnor’s spaces EG BG, show → BG is bundle, it c...

In this paper, it is proved that certain stable rank-3 vector bundles can be written as extensions of line bundles and stable rank-2 bundles. As an application, we show the rationality of certain moduli spaces of stable rank-3 bundles over the projective plane P 2 .
