Grassmannians,Calibrations and Five-Brane Intersections
G. Papadopoulos, A. Teschendorff
We present a geometric construction of a new class of hyper-Kahler manifolds with torsion. This involves the superposition of the four-dimensional hyper-Kahler geometry with torsio…

Multi-angle Five-Brane Intersections
G. Papadopoulos, A. Teschendorff
We find new solutions of IIA supergravity which have the interpretation of intersecting NS-5-branes at -angles on a string preserving at least 3/32 of supersymmetry. We show…

Instantons at Angles
G. Papadopoulos, A. Teschendorff
We interpret a class of 4k-dimensional instanton solutions found by Ward, Corrigan, Goddard and Kent as four-dimensional instantons at angles. The superposition of each pair of fou…
