Introduction to Analysis
One might be led to conjecture that the limit of a convergent sequence is always
an accumulation point of the range of the sequence. To see that this is false,
consider the sequence {a„}~=i where a„ = 1 for all n. This sequence converges to
1, ...
A point x of a topological space X will be called a 1-accumulation point of a set S
in X if Na, n S is infinite for every neighborhood of x. This notion was first
introduced by Hausdorff who used the expression B-accumulation pomt.

Elementary Classical Analysis
Another useful way to determine whether or not a set is closed is based on the
concept of an accumulation point. 2.4.1 Definition A point x in a metric space M is
called an accumulation point of a set A C M if every open set U containing x ...

Counterexamples in Topology
In this case, p is called an accumulation point of the sequence. It is possible that
a sequence has uncountably many limit points (Example 4), both a limit point and
an accumulation point- that is not a limit point (Example 53), or a single ...

A point x is an accumulation point (sometimes called cluster point or limit point) of
a subset A of a topological space (Xfl) iff every neighborhood of x contains points
of A other than x. Then it is true that each neighborhood of a point x intersects ...
Since k = 0, 0' = R, we conclude that the sets R and 0 are both open and closed.
Accumulation Point (Limit Point). Let us consider a subset A C R. A point a C R is
an accumulation point or a limit point of A if and only if every neighbourhood of a

Elementary Real Analysis
4.2.4 Show that no interior point of a set can be a boundary point, that it is
possible for an accumulation point to be a boundary point, and that every isolated
point must be a boundary point. 4.2.5 Let E be a nonempty set of real numbers
that is ...

Suppose X is a metric space, z ∈ X and S is a subset of X. Then z is called an
accumulation point or a limit point of S in X if, and only if, dist(z,S\{z}) = 0. The
collection of all accumulation points of S in X will be denoted by acc(S), or by
accX(S) ...
