Associativity of the Baker-Campbell-Hausdorff formula
Updated: 2011-10-29 20:25:13
Let be a finite-dimensional Lie algebra (over the reals). Given two sufficiently small elements of , define the right Baker-Campbell-Hausdorff-Dynkin law where , is the adjoint map , and is the function , which is analytic for near . Similarly, define the left Baker-Campbell-Hausdorff-Dynkin law where . One easily verifies that these expressions are well-defined [...]

Infinitude of Primes Via Lower Bounds: the lower bound on pi(x) shows that as xgrows, so does pi(x)
This month marks the 50th issue of symmetry magazine, which published its first issue in Oct/Nov 2004. It quickly established its own quirky style with a cover of a little girl in jammies dragging an Einstein bear.
