The ordered F-system for the F-method and differential symmetry breaking operators for

Jonathan Ditlevsen, Toshihisa Kubo, Víctor Pérez-Valdés

The paper introduces an ordered F-system for the F-method, using a symmetrization operator to handle non‑abelian nilpotent radicals, and applies this to classify differential symme…

Differential symmetry breaking operators from a line bundle to a vector bundle over real projective spaces

Toshihisa Kubo

In this paper we classify and construct differential symmetry breaking operators from a line bundle over the real projective space to a vector…

The truncated symbol of a differential symmetry breaking operator

Toshihisa Kubo, Víctor Pérez-Valdés

In this paper, we introduce the truncated symbol of a differential symmetry breaking operator between parabolically induced representatio…

On the intertwining differential operators between vector bundles over the real projective space of dimension two

Toshihisa Kubo, Bent Ørsted

The main objective of this paper is twofold. One is to classify and construct -intertwining differential operators between vector bundles over the real projective…

On the intertwining differential operators from a line bundle to a vector bundle over the real projective space

Toshihisa Kubo, Bent Ørsted

We classify and construct -intertwining differential operators from a line bundle to a vector bundle over the real projective space $\mathbb{RP}^{n-…
