First variation formula
WebThe first variation of area refers to the computation d d t ω t = − W t, H ( f t) g ω t + d ( ι W t ∥ ω t) in which H(ft) is the mean curvature vector of the immersion ft and Wt denotes the variation vector field ∂ ∂ t f t. Both of these quantities are vector fields along the map ft. WebConsider a variation $f: (-\epsilon,\epsilon)\times [0,a]\rightarrow M$ such that $f (s,0)=p_0$ and $f (s,a)=\phi (s)$. Let $E$ be the energy associated with $f$. By the first variation of energy formula, we have that $$\frac {E' (0)} {2}=\langle v,\gamma' (a)\rangle$$ Now, because $\phi$ is contained in $N$, we can conclude that $E' (0)=0$.
