Null vectors in logarithmic conformal field theory [PDF]
Proceedings of Non-perturbative Quantum Effects 2000 — PoS(tmr2000), 2000 The representation theory of the Virasoro algebra in the case of a logarithmic conformal field theory is considered. Here, indecomposable representations have to be taken into account, which has many interesting consequences. We study the generalization of null vectors towards the case of indecomposable representation modules and, in particular, how ...

Killing Vector Fields in Generalized Conformal β-Change of Finsler Spaces
Journal of Mathematics, 2015 We consider a Finsler space equipped with a Generalized Conformal β-change of metric and study the Killing vector fields that correspond between the original Finsler space and the Finsler space equipped with Generalized Conformal β-change of metric.

Bound states in N=2 Liouville theory with boundary and Deep throat D-branes [PDF]
, 2008 We exhibit bound states in the spectrum of non-compact D-branes in N=2 Liouville conformal field theory. We interpret these states in the study of D-branes in the near-horizon limit of Neveu-Schwarz five-branes spread on a topologically trivial circle ...

On the Tachibana numbers of closed manifolds with pinched negative sectional curvature
Дифференциальная геометрия многообразий фигур, 2020 Conformal Killing form is a natural generalization of conformal Killing vector field. These forms were extensively studied by many geometricians. These considerations were motivated by existence of various applications for these forms.

Tangent bundle geometry from dynamics: application to the Kepler problem
, 2016 In this paper we consider a manifold with a dynamical vector field and inquire about the possible tangent bundle structures which would turn the starting vector field into a second order one.

From Maxwell-Chern-Simons theory in $AdS_3$ towards hydrodynamics in 1+1 dimensions [PDF]
, 2015 We study Abelian Maxwell-Chern-Simons theory in three-dimensional $AdS$ black hole backgrounds for both integer and non-integer Chern-Simons coupling. Such theories can be derived from various string theory constructions, which we review in the present ...

A new characterization of the Euclidean sphere
Anais da Academia Brasileira de CiênciasIn this paper, we obtain a new characterization of the Euclidean sphere as a compact Riemannian manifold with constant scalar curvature carrying a nontrivial conformal vector field which is also conformal Ricci vector field.

Characterizing spheres by an immersion in Euclidean spaces
Arab Journal of Mathematical Sciences, 2017 In this paper we study compact immersed orientable hypersurfaces in the Euclidean space Rn+1 and show that suitable restrictions on the tangential and normal components of the immersion give different characterizations of the spheres.

Symmetries of supergravity backgrounds and supersymmetric field theory
Journal of High Energy Physics, 2020 In four spacetime dimensions, all N $$ \mathcal{N} $$ = 1 supergravity-matter systems can be formulated in the so-called U(1) superspace proposed by Howe in 1981.
