A note on a homological epimorphism whose source is a piecewise hereditary algebra
Takuma Aihara
We study a homological epimorphism of proper dg algebras and show that if the source is a finite dimensional piecewise hereditary algebra, then the target is derived equivalent to…

Examples of tilting-discrete symmetric algebras
Takuma Aihara
We give several examples of tilting-discrete symmetric algebras; in particular, one explores which algebra has tilting-discrete trivial extension. We provide a counter example of t…
