Central Extensions of Some Lie Algebras
We consider three Lie algebras: Der C((t)), the Lie algebra of all derivations on the algebra C((t)) of formal Laurent series; the Lie algebra of all differential operators on C((t)); and the Lie algebra of all differential operators on C((t)) ⊗ Cn. We prove that each of these Lie algebras has an essentially unique nontrivial central extension. The Lie algebra of all derivations on the Laurent ...
متن کاملNatural Central Extensions of Groups
Given a group G and an integer n ≥ 2 we construct a new group e K(G, n). Although this construction naturally occurs in the context of finding new invariants for complex algebraic surfaces, it is related to the theory of central extensions and the Schur multiplier. A surprising application is that Abelian groups of odd order possess naturally defined covers that can be computed from a given cov...
متن کاملSemiversal Central Extensions of Groups
We generalise the concept of universal central extensions for perfect groups to arbitrary finite groups. This construction, called the semiversal central extension of the group, has the property that it contains every cover of this group as a subquotient.
متن کاملSimplifying the Form of Lie Groups Admitted by a Given Differential Equation
Rather general results are obtained for determining the nature of infinitesimal generators which can be admitted by a given differential equation. Simple criteria are given to determine whether or not (1) the infinitesimals of independent variables can depend only on independent variables and (2) the infinitesimal of the dependent variable can depend at most linearly on the dependent variable. ...
متن کاملClassification of Second-order Ordinary Differential Equations Admitting Lie Groups of Fibre-preserving Point Symmetries
We use Elie Cartan's method of equivalence to give a complete classification, in terms of differential invariants, of second-order ordinary differential equations admitting Lie groups of fibre-preserving point symmetries. We then apply our results to the determination of all second-order equations which are equivalent, under fibre-preserving transformations, to the free particle equation. In ad...
