Let $M_\Sigma$ be an $n$-dimensional Thom-Mather stratified space of depth $1$. We denote by $\beta M$ the singular locus and $L$ associated link. In this paper we study problem when such a can endowed with wedge metric positive scalar curvature. relate to recent work on index theory spaces, giving first obstruction existence in terms $\alpha$-class $\alpha_w (M_\Sigma)\in KO_n$. order establis...

We prove results exploring the relationship between fundamental group and second Betti number of minimal symplectic fillings lens spaces. These unify generalize several disparate facts appearing in literature. The Fibonacci numbers make a cameo appearance.
