Popis: Given a truncated path algebra $A=\frac {\Bbbk Q}{J^{k}}$ we prove that ϕ dimA = ϕ dimAop. We also compute the ϕ-dimension of A as a function of the ϕ-dimension of $\frac {\Bbbk Q}{J^{2}}$ when Q has no sources nor sinks. This allows us to bound the ϕ-dimension for truncated path algebras. Finally, we characterize A when its ϕ-dimension is equal to 1.
