Hyperkähler cones and instantons on quaternionic Kähler manifolds
Chandrashekar Devchand, Massimiliano Pontecorvo, Andrea Spiro
We present a novel approach to the study of Yang-Mills instantons on quaternionic Kähler manifolds, based on an extension of the harmonic space method of constructing instantons on…
Instantons on hyperkähler manifolds
Chandrashekar Devchand, Massimiliano Pontecorvo, Andrea Spiro
An instanton on a (pseudo-)hyperkähler manifold is a vector bundle associated to a principal -bundle with a connection whose curvature is pointwise invarian…
On pseudo-hyperkähler prepotentials
Chandrashekar Devchand, Andrea Spiro
An explicit surjection from a set of (locally defined) unconstrained holomorphic functions on a certain submanifold of (Sp_1(C) \times C^{4n}) onto the set HK_{p,q} of local isomet…
Oxidation of self-duality to 12 dimensions and beyond
Chandrashekar Devchand
Using (partial) curvature flows and the transitive action of subgroups of O(d,Z) on the indices {1,...,d} of the components of the Yang-Mills curvature in an orthonormal basis, we…
Superconformal Algebras and Supersymmetric Integrable Flows
Christoph Sachse, Partha Guha, Chandrashekar Devchand
This paper has been withdrawn by the authors. Because of a misunderstanding, the paper was submitted prematurely to the arXiv. A replacement will follow.
Ternutator Identities
Chandrashekar Devchand, David Fairlie, Jean Nuyts +1
The ternary commutator or ternutator, defined as the alternating sum of the product of three operators, has recently drawn much attention as an interesting structure generalising t…
