Problem 2. Let C R² be a bounded smooth domain and p, 4 € C²(N). Consider a vector field v = (v₁, v₂): → R2 such that v E C¹ (N) and V· v=0. at √ (v(x) · Vp(x)) y(x) dæ - √ (v(x) · Vy(x)) p(x) dx . Ω (2) Assume now that p(t, ∙) E C'! (N) solves dtp + v · Vp = 0. Show that d 1/√₁\p(t, x) |²dx = 0. (1) Prove that ==
