Harmonic approach and quaternionic Taub-NUT metric
We use the harmonic space technique to construct explicitly a quaternionic extension of the Taub-NUT metric. It depends on two parameters, the first being the Taub-NUT ‘mass’ and the second one the cosmological constant. We compare the metric constructed with those available in the literature.
