Let A = c[Q]/I be a finite dimensional quotient of a path algebra over a quiver Q, with I being the ideal of relations.

Is it true that the I-adic completion of A has finite homological dimension?

    $\begingroup$ Do you really mean the $I$-adic completion of $A$, or do you mean the $I$-adic completion of $c[Q]$? (The ideal $I$ "becomes zero" in the factor algebra $A$.) $\endgroup$ Jul 31, 2013 at 14:44
  • $\begingroup$ To continue Manny's question, another thing you might mean is: the completion of A with respect to the ideal of all arrows. That is the completion which I have seen used (e.g., in representations of quivers with potential). $\endgroup$ Aug 15, 2013 at 4:53
  • $\begingroup$ You're right: I meant the I-adic completion of c[Q]. $\endgroup$
