Odd Jacobi manifolds and Loday-Poisson brackets
In this paper we construct a non-skewsymmetric version of a Poisson bracket
on the algebra of smooth functions on an odd Jacobi supermanifold. We refer to
such Poisson-like brackets as Loday-Poisson brackets. We examine the relations
between the Hamiltonian vector fields with respect to both the odd Jacobi
structure and the Loday-Poisson structure. Furthermore, we show that the
Loday-Poisson bracket satisfies the Leibniz rule over the noncommutative
product derived from the homological vector field.Comment: 18 pages. Further comments added and slight rearrangement of the

Modular classes of Q-manifolds: a review and some applications
A Q-manifold is a supermanifold equipped with an odd vector field that
squares to zero. The notion of the modular class of a Q-manifold -- which is
viewed as the obstruction to the existence of a Q-invariant Berezin volume --
is not well know. We review the basic ideas and then apply this technology to
various examples, including -algebroids and higher Poisson
manifolds.Comment: 11 pages. Comments are welcome
Odd Jacobi manifolds: general theory and applications to generalised Lie algebroids
In this paper we define a Grassmann odd analogue of Jacobi structure on a
supermanifold. The basic properties are explored. The construction of odd
Jacobi manifolds is then used to reexamine the notion of a Jacobi algebroid. It
is shown that Jacobi algebroids can be understood in terms of a kind of curved
Q-manifold, which we will refer to as a quasi Q-manifold.Comment: 35 pages. This preprint is an amalgamation of the earlier preprints
