Let {An} be a sequence of nuclear RFD C ∗ -algebras such that An ⊂ An+1 and A is the closure of ∪nAn .
Classification of simple $C^*$-algebras of tracial topological rank zero
Theorem 4.1 (Theorem 5.9 in [Ln8]) Let A be a separable C ∗ -algebra satisfying UCT such that A is the closure of an increasing sequence {An} of RFD C ∗ -algebras and B be a unital nuclear separable C ∗ -algebra.
Classification of simple $C^*$-algebras of tracial topological rank zero
Kirchberg ([BK1] and [BK2]) that every strong NF C ∗ -algebra is an inductive limit of residually finite dimensional (RFD) C ∗ -algebras.
Classification of simple $C^*$-algebras of tracial topological rank zero
It remains open whether this condition is automatically satisfied by residually finite-dimensional algebras, or any simple nuclear C ∗ -algebras which can be written as inductive limits of RFD C ∗-algebras satisfying this condition.
Classification of simple C*-algebras and higher dimensional noncommutative tori
In Christensen, Foxby, and Frankild introduced the large restricted flat dimension which is denoted by Rfd and it is defined by the formula Rfd RM = sup{i|Tor R i (L, M ) 6= 0 for some R-module L with fd RL < ∞}.
Homological flat dimensions
Because in this case we have CM ∗ fd RM = Rfd RM = Rfd bR (M ⊗R bR) = CM ∗ fd bR (M ⊗R bR), in which the first and the last equalities follow from Theorem 3.3, and the middle one follows from [30, (8.5)].
Homological flat dimensions
Now the equalities CM ∗ fd RM = Rfd RM = Rfd RM = CM ∗ fd RM , where the second equality follows from [39, (3.11)], complete the proof of the first inequality in the assertion of the Theorem.
Homological flat dimensions
CIfd RM = n + Rfd RM = Rfd RM = CIfd RM , where the second one holds by [42, (3.6)] complete the proof.
Homological flat dimensions
Choose a prime ideal p ∈ Spec (R) such that Rfd RM = depth Rp − depth RpMp .
Homological flat dimensions
Rfd RM + depth RM = depth R for every R-module M of finite depth. (ii) R is a Cohen-Macaulay ring and depth RM ≤ grade (p, M ) + dim R/p for every R-module M of finite depth, and for al l p ∈ Spec (R).
Homological flat dimensions
A C ∗ -algebra A is called residual ly finite-dimensional (RFD) if it admits a separating family of finite-dimensional representations.
Representations of residually finite groups by isometries of the Urysohn space
For instance, the full group C ∗ algebra C ∗ (F ) of the non-abelian free group (on any number of generators) is RFD, this is a result by Choi .
Representations of residually finite groups by isometries of the Urysohn space
While the group F2 × F2 is of course residually finite, residual finiteness of a group Γ is in general insufficient for the algebra C ∗ (Γ) to be RFD .
