The first Hochschild (co)homology when adding arrows to a bound quiver algebra
Claude Cibils, Marcelo Lanzilotta, Eduardo N. Marcos +2
We provide a formula for the change of the dimension of the first Hoch\-schild cohomology vector space of bound quiver algebras when adding new arrows. For this purpose we show tha…
