GR lives without a notion of an "inertial frame" and is doing fine.
To search for an inertial frame you have first to define its
meaning.

I have already done that for you. If you disagree with it,
which apparently you do, then argue that and not that I
have yet to define it. I have said that I-frames are not
real objects, but a figment of our imaginations, so we do
not "search" for I-frames, we create them.

And this is a definition? At best, it is a phrase which
defines some of its properties.

If you don't like mine, show us yours, then.

I can live without this notion, so I don't have to define it.

Suit yourself, you're the one who brought it up, remember? "To
search for an inertial frame you have first to define its meaning."

As I recall, the OP referred to SR, not GR.

In a thread about the CMBR SR is not sufficient.

The CMBR is not covered by SR.

Right, that explains this topic's title.

That is an acknowledged fact, the CMBR exists
in an expanding universe which is outside the
domain of applicability of SR.

Not necessarily. AE put SR out ... He did not ...
Note that he did not say ...

AE's words are irrelevant.

That's your opinion, but I disagree.

We have two theories,
SR and GR, and the expansion of the universe can
be described appropriately only in GR (or other
metric theories of gravity), but not in SR.

No, not so. SR is based on relative motion and the
expansion process is based on observed relative
motion. What more do you want in order to understand
that the cbr is within the domain of applicability of SR?
