Tight maps and holomorphicity, exceptional spaces
Oskar Hamlet, Takayuki Okuda
We show that there are no tight nonholomorphic maps from irreducible domains into exceptional codomains, the only exception being the already known tight nonholomorphic maps from t…

Smallest complex nilpotent orbits with real points
Takayuki Okuda
Let us fix a complex simple Lie algebra and its non-compact real form. This paper focuses on non-zero adjoint nilpotent orbits in the complex simple Lie algebra meeting the real fo…
