Unoriented skein exact triangles in equivariant singular instanton Floer theory

Aliakbar Daemi, Christopher Scaduto

Equivariant singular instanton Floer theory is a framework that associates to a knot in an integer homology 3-sphere a suite of homological invariants that are derived from circle-…

Computing $ν$ -invariants of Joyce's compact $G_{2}$ -manifolds

Christopher Scaduto

Crowley and Nordström introduced an invariant of $G_{2}$ -structures on the tangent bundle of a closed 7-manifold, taking values in the integers modulo 48. Using the spectral descript…

Niemeier lattices, smooth 4-manifolds and instantons

Christopher Scaduto

We show that the set of even positive definite lattices that arise from smooth, simply-connected 4-manifolds bounded by a fixed homology 3-sphere can depend on more than the ranks…
