several applications, especially in pharmaceutical and dermo-cosmetic industries. It has …

Reduction of Courant algebroids and generalized complex structures

H Bursztyn, GR Cavalcanti, M Gualtieri - Advances in Mathematics, 2007 - Elsevier
We present a theory of reduction for Courant algebroids as well as Dirac structures, generalized
complex, and generalized Kähler structures which interpolates between holomorphic …

New aspects of the ddc-lemma

GR Cavalcanti - arXiv preprint math/0501406, 2005 - arxiv.org
We produce examples of generalized complex structures on manifolds by generalizing results
from symplectic and complex geometry. We produce generalized complex structures on …

Generalized complex geometry and T-duality

GR Cavalcanti, M Gualtieri - arXiv preprint arXiv:1106.1747, 2011 - arxiv.org
We describe how generalized complex geometry, which interpolates between complex and
symplectic geometry, is compatible with T-duality, a relation between quantum field theories …

Generalized complex structures on nilmanifolds

GR Cavalcanti, M Gualtieri - arXiv preprint math/0404451, 2004 - arxiv.org
We show that all 6-dimensional nilmanifolds admit generalized complex structures. This
includes the five classes of nilmanifold which admit no known complex or symplectic structure. …

Examples and counter‐examples of log‐symplectic manifolds

GR Cavalcanti - Journal of Topology, 2017 - Wiley Online Library
We study topological properties of log‐symplectic structures and produce examples of compact
manifolds with such structures. Notably, we show that several symplectic manifolds do …

Stable generalized complex structures

GR Cavalcanti, M Gualtieri - Proceedings of the London …, 2018 - Wiley Online Library
A stable generalized complex structure is one that is generically symplectic but degenerates
along a real codimension two submanifold, where it defines a generalized Calabi–Yau …

[HTML][HTML] The decomposition of forms and cohomology of generalized complex manifolds

GR Cavalcanti - Journal of Geometry and Physics, 2006 - Elsevier
We study the decomposition of forms induced by a generalized complex structure giving a
complete description of the bundles involved and, around regular points, of the operators ∂ …

Symplectic resolutions, Lefschetz property and formality

GR Cavalcanti, M Fernández, V Munoz - Advances in Mathematics, 2008 - Elsevier
We introduce a method to resolve a symplectic orbifold(M,ω) into a smooth symplectic manifold
(M,ω). Then we study how the formality and the Lefschetz property of (M,ω) are compared …

Blow‐up of generalized complex 4‐manifolds

GR Cavalcanti, M Gualtieri - Journal of Topology, 2009 - Wiley Online Library
We introduce blow‐up and blow‐down operations for generalized complex 4‐manifolds.
Combining these with a surgery analogous to the logarithmic transform, we then construct …
