This used postcard bears the flag of the British Empire and was posted around the time of the First World War. The half penny stamp affixed to the postcard bears the red cross of the Red Cross Society. A fund raising ...
Minimal matrices and the corresponding minimal curves on flag manifolds in low dimension
(Elsevier Science Inc, 2009-04)
In general C*-algebras, elements with minimal norm in some equivalence class are introduced and characterized. We study the set of minimal hermitian matrices, in the case where the C*-algebra consists of 3 × 3 complex ...
Invariant almost complex structures on real flag manifolds
(Springer Heidelberg, 2018-12)
In this work, we study the existence of invariant almost complex structures on real flag manifolds associated to split real forms of complex simple Lie algebras. We show that, contrary to the complex case where the invariant ...
Quantum toric degeneration of quantum flag and Schubert varieties
(Springer, 2020-09)
We show that certain homological regularity properties of graded connected algebras, such as being AS-Gorenstein or AS-Cohen–Macaulay, can be tested by passing to associated graded rings. In the spirit of noncommutative ...

Vector fields on osp2m+1|2n(c)-flag supermanifolds
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE MATEMÁTICAUFMG, 2019)
Calculamos as superálgebras de Lie de campos vetoriais holomórficos em supervariedades de bandeira isotrópicas de tipo máximo correspondente à superálgebra de Lie osp2m − 1 | 2n (C).
Vector fields on Pi-symmetric flag supermanifolds
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE MATEMÁTICAUFMG, 2016-06)
O principal resultado deste trabalho é o cálculo das superálgebras de Lie de campos vetoriais holomórficos nas supervariedades com sinalizadores simétricos Pi complexas, introduzidas por Yu. I.Manin. Provamos que, com uma ...
