Bulk to Boundary Relation Between Topological Models and Supergravity Theories
I. V. Lavrinenko
We establish a direct correspondence between certain higher-rank p-form Chern-Simons topological type theories in the bulk of a manifold with boundary and particular sectors of sup…
Superdualities, Brane Tensions and Massive IIA/IIB Duality
I. V. Lavrinenko, H. Lu, C. N. Pope +1
The gauge transformations of p-form fields in supergravity theories acquire a non-commuting character when one introduces potentials both for the theory's original field strengths…
U-duality as General Coordinate Transformations, and Spacetime Geometry
I. V. Lavrinenko, H. Lu, C. N. Pope +1
We show that the full global symmetry groups of all the D-dimensional maximal supergravities can be described in terms of the closure of the internal general coordinate transformat…
Euclidean-signature Supergravities, Dualities and Instantons
E. Cremmer, I. V. Lavrinenko, H. Lu +3
We study the Euclidean-signature supergravities that arise by compactifying D=11 supergravity or type IIB supergravity on a torus that includes the time direction. We show that the…
Fibre Bundles and Generalised Dimensional Reduction
I. V. Lavrinenko, H. Lu, C. N. Pope
We study some geometrical and topological aspects of the generalised dimensional reduction of supergravities in D=11 and D=10 dimensions, which give rise to massive theories in low…
Harmonic superpositions of non-extremal p-branes
I. V. Lavrinenko, H. Lu, C. N. Pope +1
The plot of allowed p and D values for p-brane solitons in D-dimensional supergravity is the same whether the solitons are extremal or non-extremal. One of the useful tools for rel…
