A higher-dimensional analogue of the notion of vertex algebra, called that of axiomatic G n -vertex algebra, is formulated with Borcherds' notion of G-vertex algebra as a motivation. Some examples are given and certain analogous duality properties are proved. It is proved that for any vector space W

β¦ Synopsis
Mi --N be a principal fiber bundle over N with structure group IR+. Given a symplectic form, co, on M, we will call the pair (M, A) a symplectic cone if, for every aΒ£ER+, the diffeomorphism, r a , of M associated with a satisfies (4.4) Ta = a D . A problem which we have considered in several previous papers ([2], [31, [4], [51) is the "quantization problem" for symplectic cones. Roughly speaking this problem consists of associating with M an algebra of operators, A, and a symbolic calculus for which the symbols of the operators belonging to A are functions on M. For instance if M is the punctured cotangent bundle of a compact manifold B: M = TB def T*B -O the ring of pseudodifferential operators on B has such a symbolic calculus. Therefore, the quantization problem consists of constructing something like a ring of pseudodifferential operators for any symplectic cone, MI. One

A finite Abelian group G is partitioned into subsets which are translations of each othtr. A binary operation is defined on these sets in a way which generalizes the quotient group operation. Every finite Abelian group can be realized as such a generalized quotient with G cyclic.
