| contents | The notion of asymptotic space for an unbounded metric space has been introduced by Micha Gromov in 1980s. It is intended to capture the structure of a metric space at infinity. The most comprehensive definition of asymptotic space is given in the lahguage of Nonstandard Analysis (NSA). It turns out that the asymptotic space depends on the underlying nonstandard extension of the standard universe. This paper contains the exhaustive description of asymptotic spaces of the Lobachevski plane which turns ourt to be an R-tree. However, there turn out to be a plenty of different nonisometric asymptotic spaces, including the spaces of high cardinality. |
