An Introduction to -Algebras and their Homotopy Theory

A Kraft, J Schnitzer - arXiv preprint arXiv:2207.01861, 2022 - arxiv.org
In this review we give a detailed introduction to the theory of (curved) $ L_\infty $-algebras
and $ L_\infty $-morphisms. In particular, we recall the notion of (curved) Maurer-Cartan …

Algebroid structures on para-Hermitian manifolds

D Svoboda - Journal of Mathematical Physics, 2018 - pubs.aip.org
We present a global construction of a so-called D-bracket appearing in the physics literature
of Double Field Theory (DFT) and show that if certain integrability criteria are satisfied, it can …

Finite deformations from a heterotic superpotential: holomorphic Chern-Simons and an L∞ algebra

A Ashmore, X De La Ossa, R Minasian… - Journal of High Energy …, 2018 - Springer
A bstract We consider finite deformations of the Hull-Strominger system. Starting from the
heterotic superpotential, we identify complex coordinates on the off-shell parameter space …

Shifted derived Poisson manifolds associated with Lie pairs

R Bandiera, Z Chen, M Stiénon, P Xu - Communications in Mathematical …, 2020 - Springer
We study the shifted analogue of the “Lie–Poisson” construction for L_ ∞ L∞ algebroids
and we prove that any L_ ∞ L∞ algebroid naturally gives rise to shifted derived Poisson …

Deformations of Lagrangian -submanifolds

In this paper we prove graded versions of the Darboux Theorem and Weinstein's tubular
neighbourhood Theorem in order to study the deformation theory of Lagrangian $ Q …

The Weak Graded Lie 2-Algebra of Multiplicative Forms on a Quasi-Poisson Groupoid

Z Chen, H Lang, Z Liu - Communications in Mathematical Physics, 2024 - Springer
We present a construction of weak graded Lie 2-algebras associated with quasi-Poisson
groupoids. We also establish a morphism between this weak graded Lie 2-algebra of …

The deformation L∞ algebra of a Dirac–Jacobi structure

AG Tortorella - Differential Geometry and its Applications, 2022 - Elsevier
We develop the deformation theory of a Dirac–Jacobi structure within a fixed Courant–
Jacobi algebroid. Using the description of split Courant–Jacobi algebroids as degree 2 …
