REGULAR STONES OF WILD HEREDITARY ALGEBRAS

[摘要] If A is a finite-dimensional wild herediary algebra we study the class of regular components containing stones of quasi-length two, where a stone is a brick without self-extensions. We show that there are only finitely many non-sincere components of this type and, provided the lagebra has elementary modular with self-extensions, no sincere component with stones of quasi-length two.
