CSIR NET June 2025 · Part B (3 Marks)Complex Analysis, Algebra & Topology#the-2-pi-r-arc-length-factor-forces-f-to-vanish-so-c-is-exactly-0

Let f:C→Cf : \mathbb{C} \to \mathbb{C} be a polynomial map. For R > 0, let γR:[0,1]→C\gamma_R : [0, 1] \to \mathbb{C} be the map t ↦ Re2πitRe^{2\pi{}it}. Suppose that there exists c∈Rc \in \mathbb{R} such that ∫01\int_{0}^{1} |(f ∘ γR)(t)γR′(t)\gamma_R)(t) \gamma'_R(t)| dt → c as R→∞R \to \infty. Which of the following statements is FALSE?
