Nakayama algebras and Fuchsian singularities
Helmut Lenzing, Hagen Meltzer, Shiquan Ruan
This present paper is devoted to the study of a class of Nakayama algebras given by the path algebra of the equioriented quiver subject to the nilpotency de…
Modules attached to extension bundles
Dawid Kędzierski, Hagen Meltzer
In this article we study modules over wild canonical algebras which correspond to extension bundles [9] over weighted projective lines. We prove that all modules attached to extens…
The braid group action on exceptional sequences for weighted projective lines
Edson R. Alvares, Eduardo N. Marcos, Hagen Meltzer
We give a new and intrinsic proof of the transitivity of the braid group action on the set of full exceptional sequences of coherent sheaves on a weighted projective line. We do no…
Exceptional modules over wild canonical algebras
Dawid Edmund Kędzierski, Hagen Meltzer
We show that ''almost all'' exceptional modules over wild canonical algebra can be described by matrices having coefficients , where are elements from the p…
Matrix factorizations for domestic triangle singularities
Dawid Edmund Kędzierski, Helmut Lenzing, Hagen Meltzer
Working over an algebraically closed field of any characteristic, we determine the matrix factorizations for the --- suitably graded --- triangle singularities …
Triangle singularities, ADE-chains, and weighted projective lines
Dirk Kussin, Helmut Lenzing, Hagen Meltzer
We investigate the triangle singularity , or , attached to a weighted projective line given by the weight triple . We investigate the st…
