Nope, once again " as an indivisible object" it is not "at" any " given domain" less then itself. Yet can be a union of segments, rays or points "at" any number of given domains.
Once again you demonstate your inability to get indivisible elements A and B, such that B is at
AND not at A, where A is at
XOR not at B.
A linkage among indevisible elements provides the existence of complex objects that are understood in terms of collections.
Sice you have no Meta view of the considered subject, you are missing the following:
I wish to share with you some Meta view of the Mathematical Science, which does not follow after some basic agreed notions. Let us start by using
Gottlob Frege's notion about X≠X. He defined number 0 as the amount of the objects of the class of all X≠X (
Frege defined the number 0 as the number of the concept not being self-identical,
(
http://plato.stanford.edu/entries/frege/ ) )
0 is not equivalent to Nothing, because 0 is, after all something, called a number. But it does not mean that Emptiness or Nothing can't directly be used in order to do some Math. Let us follow this notion by re-examine, for example, the notion of the empty set:
(X=X) means: "X exists" or "X is true"
(X≠X) means: "X does not exist" or "X is false"
According to this Meta view, there are different versions of the empty set as follows:
p case:
[latex]$$$
\exists z \, \forall (x \ne x) \, (x \ne x) \rightarrow ((x \ne x) \in z)$$$[/latex]
By p case version,
z exists as an empty set only if the non-existing (nothing) "belongs" to it, but then this version does not cover the case of the existing things that do not belong to
z.
q case:
[latex]$$$
\exists z \, \forall (x = x) \, (x = x) \rightarrow ((x = x) \notin z)$$$[/latex]
By q case version,
z exists as an empty set only if the existing things (something) do not belong to it, but then
z is one of the exiting things that are used to define the existence of
z, which is a circular reasoning.
As demonstrated, if Non-existence (Nothing or Emptiness) is taken directly as "a legitimate participator" of some mathematical framework, then even an intuitive concept like The empty set, is shown by a now light,
because by the meaning of (X≠X) we are able to understand the meaning of (X=X), as shown above.

Let us do a further step and look at the Mathematical Science by using a Meta view about Deduction. From this Meta view, some mathematical theory is (hopefully) a consistent framework of unproved context-dependent collection of decelerations, known as axioms.
Since the development of Non-Euclidian geometries and Gödel's Incompleteness theorems, most of the mathematicians are actually reinforce the deductive and context-dependent nature of their mathematical work, such that no systematic research is done in order to understand better the cross-contexts linkages that are invented\discovered from time to time among, so called, "mathematical branches".
Actually a phrase like "mathematical branches" (if related to context-dependent frameworks) is misleading, because there is no Mata view of Cross-contexts research of these Context-dependent frameworks, which rigorously and systematically demonstrates the linkage between them, such that they can be considered as "branches of a one tree" or as "organs of a one organism".
Gelfand wonders about the weak effectiveness of the mathematical science on disciplines like Biology (
http://en.wikipedia.org/wiki/Unreasonable_ineffectiveness_of_mathematics ), which is characterized by its organic nature.
Organic Mathematics (which is a non-standard view of Math) is an attempt to develop a Meta view of the Mathematical Science, which its aim is to discover\invent the paradigm of the organic notion of the Mathematical Science.
By the current paradigm, which is generally based on Deduction, any given mathematician (or group of mathematicians) is asked to invent\discover his\their Context-dependent framework by avoiding any "mutations" of already agreed terms. I believe that one of the possible answers to
Gelfand's remark is the impossibility of "mutations" among deductive frameworks.
The deductive-only paradigm of the Mathematical science for the past 3,500 years can't agree with "mutations" of already accepted terms.
It has to be stressed that mutations are changes of basic terms that may fundamentally change a given organism (
where the term "organism" is generalized to any abstract or non-abstract framework).
Furthermore, these "mutations" are not destructive-only exactly because of the cross-context and non-local nature of the organism as a whole with respect to its organs, which uses the mutations for further development of itsef as a complex phenomanon.
The notion of Non-locality is essential to Cross-contexts frameworks like organic systems, and it is essentially forbidden by the deductive-only paradigm.
By using Cross-contexts framework of the mathematical science, concepts like (Non-existence=Fallacy) or (Existence=Truthfulness) is used, as previously shown.
Let us draw a preliminary view of a Cross-contexts' axiomatic framework.
According to it, total notions like Emptiness and Fullness are defined, such that Emptiness is weaker than the notion of Collection and Fullness is stronger than the notion of Collection. It has to be stressed that the notion of Collection is a fundamental term of deductive-only frameworks, and the use of a notion like Fullness (which is the opposite of Emptiness) enables to define the non-local property of Cross-contexts' axiomatic framework.
The first version of the development of the axioms of the the paradigm of Cross-contexts framework is (the remarks are allowed at this preliminary development's state and are use to help the reader to move from the Context-dependent framework to the Cross-contexts framework. After the paradigm-shift is done, these remarks are not needed anymore):
(
Predecessor is what is less than a considered thing.
Successor is what is more than a considered thing.)
The axiom of minima:
Emptiness is that has no predecessor.
The axiom of maxima:
Fullness is that has no successor.
(
Only Emptiness does not have a predecessor in the absolute sense.
Only Fullness does not have a successor in the absolute sense.
The next axioms are at the level of the existence of collections, which is > Emptiness AND < Fullness, where > or < are the order of existence w.r.t Emptiness or Fullness.)
The axiom of existence:
Any existing thing has a predecessor.
(
y and x are place holders for an intermediate state of existence between Emptiness and Fullness.)
The axiom of infinite collection:
If x exists then y>x exists.
The axiom of Locality:
There exist y and x, such that x is at the context of y.
The axiom of Non-Locality:
There exist y and x, such that y is at AND not at the context of x.
