Resolution of -dimensional symplectic orbifolds
Lucía Martín-Merchán, Juan Rojo
We give a method to resolve 4-dimensional symplectic orbifolds making use of techniques from complex geometry and gluing of symplectic forms. We provide some examples to which the…

A K-contact simply connected 5-manifold with no semi-regular Sasakian structure
Alejandro Cañas, Vicente Muñoz, Juan Rojo +1
We construct the first example of a 5-dimensional simply connected compact manifold that admits a K-contact structure but does not admit a semi-regular Sasakian structure. For this…

Symplectic resolution of orbifolds with homogeneous isotropy
Vicente Muñoz, Juan Angel Rojo
We construct the symplectic resolution of a symplectic orbifold whose isotropy locus consists of disjoint submanifolds with homogeneous isotropy, that is, all its points have the s…
