Admissible homomorphisms and equivariant relations between weighted projective lines

Jianmin Chen, Yanan Lin, Shiquan Ruan +1

The string group acts on the category of coherent sheaves over a weighted projective line by degree-shift actions. We study the equivariant equivalence relations induced by degree-…

Tilting bundles and the "missing part" on the weighted projective line of type $(2, 2, n)$

Jianmin Chen, Yanan Lin, Shiquan Ruan

This paper classifies all the tilting bundles in the category of coherent sheaves on the weighted projective line of weight type $(2, 2, n)$ , and investigates the abelianness of th…

Tilting objects in the stable category of vector bundles on the weighted projective line of type (2,2,2,2;λ)

Jianmin Chen, Yanan Lin, Shiquan Ruan

We construct a tilting object for the stable category of vector bundles on a weighted projective line X of type (2,2,2,2;λ), consisting of five rank two bundles and one rank three…
