We establish a new universal relation between the Lie bracket and $\circ$-multiplication of tangent fields on any Frobenius (super)manifold. We use this identity in order to introduce the notion of ``weak Frobenius manifold'' which does not involve metric as part of structure. As another application, we show that the powers of an Euler field generate (a half of) the Virasoro algebra on an arbitrary, not necessarily semisimple, Frobenius supermanifold. 
On Symmetry Properties of Frobenius Manifolds and Related Lie-Algebraic Structures
TLDR
An algebraically feasible approach to solutions of the oriented associativity equations is developed based on a modification of the Adler– Kostant–Symes integrability scheme and applied to the co-adjoint orbits of the diffeomorphism loop group of the circle. Expand
Nijenhuis infinity and contractible dg manifolds
We find a minimal differential graded (dg) operad whose generic representations in $R^n$ are in one-to-one correspondence with formal germs of those endomorphisms of the tangent bundle to $R^n$ whichExpand
Frobenius manifolds and algebraic integrability
We give a short review of Frobenius manifolds and algebraic integrability and study their intersection. The simplest case is the relation between the Frobenius manifold of simple singularities, whichExpand
Frobenius∞ invariants of homotopy Gerstenhaber algebras, I
We construct a functor from the derived category of homotopy Gerstenhaber algebras, g, with finite-dimensional cohomology to the purely geometric category of so-called F∞-manifolds. The latterExpand
MULTIPLICATION ON THE TANGENT BUNDLE
Manifolds with a commutative and associative multi- plication on the tangent bundle are called F-manifolds if a unit field exists and the multiplication satisfies a natural integrability con- dition.Expand

Hermitian metrics on F-manifolds
Abstract An F -manifold is complex manifold with a multiplication on the holomorphic tangent bundle, which satisfies a certain integrability condition. Important examples are Frobenius manifolds andExpand
Some examples of non-massive Frobenius manifolds in singularity theory
Let f, g : C-2 -> C be two quasi-homogeneous polynomials. We compute the V-filtration of the restriction of f to any plane curve C-t = g(-1) (t) and show that the Gorenstein generator dx boolean ANDExpand
Calculus of multilinear differential operators, operator $L_\infty$-algebras and ${\it IBL}_\infty$-algebras
Motivated by the study of deformations of Lie bialgebraic structures, we generalize the construction of the well-known big bracket of Lecomte–Roger to encompass the case of homotopy involutive LieExpand
Manifolds with multiplication on the tangent sheaf
This is a survey of the current state of the theory of $F$--(super)manifolds $(M,\circ)$, first defined in [HeMa] and further developed in [He], [Ma2], [Me1]. Here $\circ$ is an $\Cal{O}_M$--bilinearExpand
