Deformation of 2-step Nilmanifolds with Abelian Complex Structures
C. McLaughlin, H. Pedersen, Y. S. Poon +1
We develop deformation theory for abelian invariant complex structures on a nilmanifold, and prove that in this case the invariance property is preserved by the Kuranishi process.…

Selfdual Einstein metrics with torus symmetry
David M. J. Calderbank, Henrik Pedersen
It is well known that any 4-dimensional hyperkahler metric with two commuting Killing fields may be obtained explicitly, via the Gibbons-Hawking Ansatz, from a harmonic function in…
