Isotropy index for the connected sum and the direct product of manifolds

Irina Gelbukh

A subspace or subgroup is isotropic under a bilinear map if the restriction of the map on it is trivial. We study maximal isotropic subspaces or subgroups under skew-symmetric maps…

The co-rank of the fundamental group: the direct product, the first Betti number, and the topology of foliations

Irina Gelbukh

We study $b_{1}^{'} (M)$ , the co-rank of the fundamental group of a smooth closed connected manifold $M$ . We calculate this value for the direct product of manifolds. We characterize the…
