| Research Abstract |
We have constructed various examples of algebraic twistor spaces in explicit forms, and given a characterization of them in terms of the corresponding self-dual metrics. Also we have refined the definition of minitwistor twistor spaces, and constructed various examples satisfying that property. In particular, we have constructed minitwistor spaces which are obtained from the so called Joyce metrics. There minitwistor spaces are rational surfaces which have simple structure, but usually have singularities. Moreover, we have concretely described some degenerations for significantexamples of some algebraic twistor spaces.
