Projective superspaces in practice [PDF]

Journal of Geometry and Physics, 2018
We study the supergeometry of complex projective superspaces $\mathbb{P}^{n|m}$. First, we provide formulas for the cohomology of invertible sheaves of the form $\mathcal{O}_{\mathbb{P}^{n|m}} (\ell)$, that are pull-back of ordinary invertible sheaves on the reduced variety $\mathbb{P}^n$.

On conformal supergravity and harmonic superspace [PDF]

, 2015
This paper describes a fully covariant approach to harmonic superspace. It is based on the conformal superspace description of conformal supergravity and involves extending the supermanifold M^{4|8} by the tangent bundle of CP^1. The resulting superspace M^{4|8} x TCP^1 can be identified in a certain gauge with the conventional harmonic superspace M^{4|

The Binary Invariant Differential Operators on Weighted Densities on the superspace $\mathbb{R}^{1|n}$ and Cohomology [PDF]

JOURNAL OF MATHEMATICAL PHYSICS 51, 043504 (2010), 2009
Over the $(1,n)$-dimensional real superspace, $n>1$, we classify $\mathcal{K}(n)$-invariant binary differential operators acting on the superspaces of weighted densities, where $\mathcal{K}(n)$ is the Lie superalgebra of contact vector fields. This result allows us to compute the first differential cohomology of %the Lie superalgebra $\mathcal{K}(n)$

Moduli and Periods of Supersymmetric Curves

, 2019
Supersymmetric curves are the analogue of Riemann surfaces in super geometry. We establish some foundational results about complex Deligne-Mumford superstacks, and we then prove that the moduli superstack of supersymmetric curves is a smooth complex ...

Asymmetric structuring of ceramic composite via co‐electrospun sodium cobaltite and calcium cobaltite nanoribbons

Journal of the American Ceramic Society, Volume 108, Issue 5, May 2025.
Abstract An asymmetrically structured sodium cobaltite–calcium cobaltite ceramic composite with enhanced texture was synthesized using co‐electrospinning of nanoribbons and rapid thermal processing (RTP). Long‐term stability tests revealed that embedding the unstable sodium cobaltite in the chemically more stable calcium cobaltite effectively shields ...

Exploring curved superspace [PDF]

Journal of High Energy Physics, 2012
We systematically analyze Riemannian manifolds M that admit rigid supersymmetry, focusing on four-dimensional N=1 theories with a U(1)_R symmetry. We find that M admits a single supercharge, if and only if it is a Hermitian manifold. The supercharge transforms as a scalar on M.

Pauli-Lubanski, supertwistors, and the superspinning particle

Journal of High Energy Physics, 2017
We present a novel construction of the super-Pauli-Lubanski pseudo-vector for 4D supersymmetry and show how it arises naturally from the spin-shell constraints in the supertwistor formulation of superparticle dynamics.

The BV Formalization of Chern-Simons Theory on Deformed Superspace [PDF]

Comm. Theor. Phys. 58: 704, 2012, 2012
In this paper we will study non-abelian Chern-Simons theory on a deformed superspace. We will deform the superspace in such a way that it includes the noncommutativity between bosonic and fermionic coordinates. We will first analyse the BRST and the anti-BRST symmetries of the Chern-Simons theory on this deformed superspace.

Superfield Theories in Tensorial Superspaces and the Dynamics of Higher Spin Fields

, 2004
We present the superfield generalization of free higher spin equations in tensorial superspaces and analyze tensorial supergravities with GL(n) and SL(n) holonomy as a possible framework for the construction of a non-linear higher spin field theory ...
