Fillable structures on negative-definite Seifert fibred spaces

Alberto Cavallo, Irena Matkovic ยท 2026

We classify fillable contact structures on all negative-definite star-shaped plumbings. Along the way, we show that such Seifert fibred spaces admit a unique negative maximal twisting number, and compโ€ฆ
