Negative definite spin filling and branched double covers
arXiv:2308.08022 · doi:10.2140/agt.2026.26.1655
Abstract
We investigate the negative definite spin fillings of branched double covers of alternating knots. We derive some obstructions for the existence of such fillings and find a characterization of special alternating knots based on them.
