The general (2,2) gauged sigma model with three--form flux [PDF]
, 2006 We find the conditions under which a Riemannian manifold equipped with a closed three-form and a vector field define an on--shell N=(2,2) supersymmetric gauged sigma model.

Quaternionic Kaehler Manifolds [PDF]
Transactions of the American Mathematical Society, 1982 The topological classification of 4 4 - and 8 8 - (real) dimensional compact quaternionic Kaehler manifolds is given. There is only the torus in dimension 4. In dimension 8, there are 12 homeomorphism classes; representatives are given explicitly.

Limnology and Oceanography, Volume 67, Issue S2, Page S36-S49, November 2022., 2022 Abstract Kelp forests are highly productive coastal habitats and are emerging as important sources of organic matter for other ecosystems. Although their high rates of productivity and detritus release are expected to lead to substantial export of carbon, few studies have actually quantified rates of export or the persistence of detritus.

Warped product semi-slant submanifolds in locally conformal Kaehler manifolds
Pracì Mìžnarodnogo Geometričnogo Centru, 2017 In 1994, in [13], N. Papaghiuc introduced the notion of semi-slant submanifold in a Hermitian manifold which is a generalization of CR- and slant-submanifolds. In particular, he considered this submanifold in Kaehlerian manifolds, [13]. Then, in 2007, V.

∗‐Ricci Tensor on α‐Cosymplectic Manifolds
Advances in Mathematical Physics, Volume 2022, Issue 1, 2022., 2022 In this paper, we study α‐cosymplectic manifold M admitting ∗‐Ricci tensor. First, it is shown that a ∗‐Ricci semisymmetric manifold M is ∗‐Ricci flat and a ϕ‐conformally flat manifold M is an η‐Einstein manifold. Furthermore, the ∗‐Weyl curvature tensor W∗ on M has been considered.

Financialization, common stochastic trends, and commodity prices
Journal of Futures Markets, Volume 41, Issue 12, Page 1988-2008, December 2021., 2021 Abstract Commodity financialization has been a subject of discussion since the 2008 financial crisis. It is estimated that between 2003 and 2008, index investorsʼ positions increased from $13 billion to $317 billion. Surprisingly, most studies, predominantly based on Granger‐causality testing, find no relationship between financialization and commodity

On canonscal quasi-geodesic mappings of recurrent-parabolic spaces
Pracì Mìžnarodnogo Geometričnogo Centru, 2018 The article is devoted to the problem of holomorphically projective transformations of locally conformal Kaehler manifolds. it's worth to be noted, that J. Mikes and Z.

The Collapsing Rate of the K\"ahler-Ricci Flow with Regular Infinite Time Singularity [PDF]
, 2013 We study the collapsing behavior of the Kaehler-Ricci flow on a compact Kaehler manifold X admitting a holomorphic submersion X -> S coming from its canonical class, where S is a Kaehler manifold with dim S < dim X.

Demonstratio Mathematica, 1985 The authors consider Kaehlerian manifolds whose Einstein tensor is recurrent. Some properties of such manifolds in relation to Ricci- recurrent, Bochner-recurrent, H-projective recurrent and H-concircular recurrent manifolds are studied.

Kant's a priori history of metaphysics: Systematicity, progress, and the ends of reason
European Journal of Philosophy, Volume 29, Issue 4, Page 811-826, December 2021., 2021 Abstract This paper explores Kant's conception of the relation between philosophy and its history. The idea that philosophy must account for its historical development is often associated with German Idealism. On the traditional view, the German Idealists departed from the ahistorical Kantian framework by conceiving of reason in a developmental manner,
