WebApr 11, 2024 · Abstract : In joint work with Brendan Mallery (Tufts), we introduce the notion of a "shift-similar" subgroup of the group of permutations of the natural numbers N. The definition makes use of the fact that any cofinite subset of N is canonically bijective with N, and is an analog to the well-known condition of "self-similarity" for subgroups of ... WebAny propersubgroup of the additive group R iseither its closedsubset or its densesubset. Proof. Let H be a subgroup of R. Assume w.l.o.g that H is not a closed subset of R. If possible, let us suppose that there is a basis element (a,b), which does not intersect H. Then there is a limit point x /∈ H of H in R.

For an example of a subgroup that is not an embedded Lie subgroup, consider the torus and an "irrational winding of the torus". The example shows that for some groups H one can find points in an arbitrarily small neighborhood U in the relative topology τr of the identity that are exponentials of elements of h, yet they cannot be connected to the identity wit… WebLET G be the set of closed additive subgroups of R’; of {0}, Z, R, RX Z, R* or Z’. _ each FE is isomorphic to one By identifying P E G with r = P U {m} C R’ U {=} = S*, we induce on G the Haus- dorff metric on the space of closed subsets of S’.
