comment Non-Abelian Fourier Analysis
You may want to read the paper "L'algebre de Fourier d'un groupe localement compact" by P. Eymard. It doesn't give you inversion formula, but it is the C*-algebraic framework generalizing Fourier analysis to non-abelian groups.

comment Noncommutative HKR theorem
A long time ago, I read something about it in Loday's book "cyclic homology", see Section 3.4.

comment Specific Reference? Noncommutative topology and C^* algebras
I doubt if there is a single reference for all the entries of the table in the above link. Perhaps, you should try to understand the Gelfand duality first and then try to prove these equivalences.

comment Motivation behind the definition of hochschild cohomology
Hochschild (co)homology can be used to computed (co)homology of groups, see my post here.

The first item has already been discussed in the comments.

comment Characterization of ideals in the bounded operators
In fact, every non-zero two sided ideal of $B(H)$ contains the ideal of finite rank operators.

comment Algebraic K-theory can be seen as a generalization of Linear algebra?
I think half of mathematics can be thought as a generalization of Linear algebra. You can get a better answer if you specify your question a little bit more!

Although you have already got some insightful comments and answers here, your question fits better in academia.stackexchange.com.

comment Is the space of *-homomorphisms between two $C^*$-algebras locally path connected
It is not a counterexample for the question, because any discrete space is locally path connected.

comment Is the space of *-homomorphisms between two $C^*$-algebras locally path connected
There is an ambiguity in your question. In your question $\epsilon$ is independent of $f$ and $G$. But the locally path connected means for every homomorphism $f$, there is an $\epsilon>0$ such that if $g$ is a homomorphism and $d(f,g)<\epsilon$, then there is a continuous homotopy between $f$ and $g$. If this second version is what you mean, you should edit your question.

comment Lattices in general totally disconnected locally compact groups
@HJRW: Yes, you are right, unless the other summand is a discrete group.

comment Lattices in general totally disconnected locally compact groups
I am wondering can one reduce simplicity with the condition that there is no open normal subgroup in the TDLC group? Is it still an interesting (and non-trivial) question to look for TDLC groups without lattices?
