| 2010-08-30 16:43:09 -0500 | answered a question | Does Math like $f (x) = e^{- x}$ work on askbot? (Just testing -- pay no attention to the man behind the curtain.) ${{G}_{-}}\cong {{N}_{-}}\times (U(n-1)\times {{\mathbb{R}}^{+}})$. Note the analogy with the Euclidean similarity group $\text{Sim}({{\mathbb{R}}^{2n+1}})={{\mathbb{R}}^{2n+1}}\times (\mathrm{O}(2n+1)\times {{\mathbb{R}}^{+}})$. |
