A Polynomial Invariant of Strongly Involutive Links
Carlo Collari, Paolo Lisca
We introduce a new two-variable polynomial invariant \(P^e\) of strongly involutive links, uniquely characterised by equivariant skein relations and naturally viewed as an equivari…
Strongly Invertible Legendrian Links
Carlo Collari, Paolo Lisca
We introduce and study strongly invertible Legendrian links in the standard contact three-dimensional space. We establish the equivariant analogs of basic results separately well-k…
Horizontal decompositions, II
Paolo Lisca, Andrea Parma
We complete the classification of the smooth, closed, oriented 4-manifolds having Euler characteristic less than four and a horizontal handlebody decomposition of genus one. We use…
Horizontal decompositions, I
Paolo Lisca, Andrea Parma
We show that every smooth, closed, orientable 4-manifold X admits a special kind of handlebody decomposition that we call horizontal. We classify the closed 4-manifolds with the si…
On almost complex embeddings of rational homology balls
Paolo Lisca, Andrea Parma
We use elementary arguments to prove that none of the Stein rational homology 4-balls shown by the authors and Brendan Owens to embed smoothly but not symplectically in the complex…
On Stein rational balls smoothly but not symplectically embedded in CP^2
Paolo Lisca, Andrea Parma
We extend recent work of Brendan Owens by constructing a doubly infinite family of Stein rational homology balls which can be smoothly but not symplectically embedded in CP^2.
