چکیده

For an element $\Psi$ in the graded vector space $\Omega^*(M, TM)$ of tangent bundle valued forms on a smooth manifold $M$, $\Psi$-submanifold is defined as submanifold $N$ $M$ such that $\Psi_{|N} \in \Omega^*(N, TN)$. The class $\Psi$-submanifolds encompasses calibrated submanifolds, complex submanifolds and all Lie subgroups compact groups. carries natural algebra structure, given by Frolicher-Nijenhuis bracket $[-,- ]^{FN}$. When odd degree with $[ \Psi, \Psi]^{FN} =0$, we associate to strongly homotopy algebra, which governs formal (under certain assumptions) deformations $\Psi$-submanifold, show under assumptions these form analytic variety. As application revisit deformation theory closed $\varphi$-calibrated where $\varphi$ parallel real Riemannian manifold.

Deformations of Calibrated Submanifolds

Assuming the ambient manifold is KK ahler, the theory of complex sub-manifolds can be placed in the more general context of calibrated submanifolds, see HL]. It is therefore natural to try to extend some of the many results in complex geometry to the other calibrated geometries of HL]. In particular, the question of deformability of calibrated submanifolds is addressed here (analogous to Kodair...

Deformations of Coisotropic Submanifolds and Strong Homotopy Lie Algebroids

In this paper, we study deformations of coisotropic submanifolds in a symplectic manifold. First we derive the equation that governs C∞ deformations of coisotropic submanifolds and define the corresponding C∞-moduli space of coisotropic submanifolds modulo the Hamiltonian isotopies. This is a non-commutative and non-linear generalization of the well-known description of the local deformation sp...

un 9 4 Strongly homotopy Lie algebras Tom Lada

Strongly homotopy Lie algebras first made their appearance in a supporting role in deformation theory [11]. The philosophy that every deformation problem is directed by a differential graded Lie algebra leads, in the context of deformation theory of a differential graded algebra A, to a spectral sequence of which the E2-term is naturally a strongly homotopy Lie algebra. For a topological space ...

Examples of Homotopy Lie Algebras

We look at two examples of homotopy Lie algebras (also known as L∞ algebras) in detail from two points of view. We will exhibit the algebraic point of view in which the generalized Jacobi expressions are verified by using degree arguments and combinatorics. A second approach using the nilpotency of Grassmann-odd differential operators ∆ to verify the homotopy Lie data is shown to produce the sa...

On Deformations and Contractions of Lie Algebras

In this contributed presentation, we discuss and compare the mutually opposite procedures of deformations and contractions of Lie algebras. We suggest that with appropriate combinations of both procedures one may construct new Lie algebras. We first discuss low-dimensional Lie algebras and illustrate thereby that whereas for every contraction there exists a reverse deformation, the converse is ...
