Transforms of holomorphic maps from flag manifolds into Grassmannians
Oscar Macia, Yasuyuki Nagatomo
Building on the generalized do Carmo-Wallach theory, we construct a functorial framework for holomorphic maps from flag manifolds into Grassmannians and quadrics. Through the direc…
On quaternionic bisectional curvature
Oscar Macia, Uwe Semmelmann, Gregor Weingart
In this article we study the concept of quaternionic bisectional curvature introduced by B. Chow and D. Yang for quaternion-Kähler manifolds. We show that non-negative quaternionic…
Holomorphic isometric embeddings of complex Grassmannians into quadrics: The general case
Oscar Macia, Yasuyuki Nagatomo
The present article studies holomorphic isometric embeddings of arbitrary complex Grassmannians into quadrics, generalising results in [13]. The moduli spaces of these embeddings u…
Holomorphic isometric embeddings of the complex two-plane Grassmannian into quadrics
Oscar Macia, Yasuyuki Nagatomo
The present article studies holomorphic isometric embeddings of the complex two--plane Grassmannnian into quadrics. We discuss the moduli space of these embeddings up to gauge and…
The c-map on groups
Oscar Macia, Andrew Swann
We study the projective special Kaehler condition on groups, providing an intrinsic definition of homogeneous projective special Kaehler that includes the previously known examples…
Moduli of Einstein-Hermitian harmonic mappings of the projective line into quadrics
Oscar Macia, Yasuyuki Nagatomo
The present article studies the class of Einstein-Hermitian harmonic maps of constant Kaehler angle from the projective line into quadrics. We provide a description of their moduli…
