This Demonstration draws the one-dimensional Lie group
(α)={(exp(iθ),exp(iαθ))|θ∈}
plotted as a subgroup embedded (or immersed) in the two-dimensional torus group
2

={(exp(iθ),exp(iθ))|θ∈}
. The slope
α
is set by the direction of the velocity, and the subgroup is plotted from
θ=0
up to a maximum value set by the "length" value; this latter is the product of the "multiplier" value and the length of the velocity, so you can watch the thread grow by putting the velocity near
(0,0)
(left-bottom corner) and dragging it to longer and longer lengths.
