'Supergravity solutions: A guide for the lazy'

If I gave you some theory of my choosing and asked you to find me a
solution, a naive thing to do would be to write down some equations of
motion (long) and try to solve them (hard). A much more interesting
and fruitful approach would be to try to find some duality between the
original theory and something simpler which you know how to solve:
this is the technique we\u2019ll explore in the context of
supergravity. In particular, we\u2019ll see how dimensional reduction
can be used to generate such maps, and therefore allow us to find
solutions to our favourite supergravity theories which it would have
been difficult to obtain otherwise. We'll also consider some of the
nice geometrical structures that arise naturally from this technique.
