abstract = {Let X be a connected locally compact metric space. It is known that if X is locally connected, then the space of ends (Freudenthal ends), EX, can be represented as the inverse limit of the set (space) S(X C) of components of X C, i.e., as the inverse limit of the inverse system \[ EX = \mathop \{\lim \}\limits \_ \leftarrow (S(X\backslash C)),inclusions,CcompactinX) \]
. In this paper, the above result is significantly improved. It is shown that for a space which is not locally connected, we can replace the space of components by the space of quasicomponents Q(X C) of X C. The following result is proved: if X is a connected locally compact metric space, then \[ EX = \mathop \{\lim \}\limits \_ \leftarrow (Q(X\backslash C)),inclusions,CcompactinX) \]

AB - Let X be a connected locally compact metric space. It is known that if X is locally connected, then the space of ends (Freudenthal ends), EX, can be represented as the inverse limit of the set (space) S(X C) of components of X C, i.e., as the inverse limit of the inverse system \[ EX = \mathop {\lim }\limits _ \leftarrow (S(X\backslash C)),inclusions,CcompactinX) \]
. In this paper, the above result is significantly improved. It is shown that for a space which is not locally connected, we can replace the space of components by the space of quasicomponents Q(X C) of X C. The following result is proved: if X is a connected locally compact metric space, then \[ EX = \mathop {\lim }\limits _ \leftarrow (Q(X\backslash C)),inclusions,CcompactinX) \]
