comment Is there any relationship between the topologies of the clique complex and the independence complex?
There is no connection in general between $X(G)$ and $S^n \setminus I(G)$ for a given graph $G$. Perhaps you're more interested in classifying those $G$ for which an Alexander type theorem might hold?

comment Eilenberg-Mac lane spaces and a generalization
One candidate is just the product $K(G,n) \times K(H,m)$, so I guess you are asking for spaces with the desired property that are not homotopy equivalent to products of Eilenberg-Maclane spaces.

comment Determine the boundary points of a set of points
@IgorRivin How does image segmentation and/or persistence identify the boundary in any sense of a planar point set? One might get a one-parameter family of partitions of these points, but it isn't clear how that would help with the problem at hand.

comment Determine the boundary points of a set of points
I'm not sure how anything in EH answers the question (I have the book in front of me). Did you have any specific part of the book in mind?

comment Probability of connected graph on torus
@AnthonyQuas It seems as though the OP is saying that it is unclear how to express the probability that the graph is connected, not that there is any confusion regarding the definition of connectivity.

comment A homological criterion for collapsibility?
Taking $A$ to be a point does not give a criterion for collapsibility because the theorem says that $B$ collapses simplicially to $A$ union a bunch of stuff $B'$ in the $(m-1)$ skeleton. In order to "iterate this lemma", you would require the reduced homology of that $B'$ to also be zero, no?
