Lipschitz regularity at infinity and affine linearity conjecture

From papers

Let XCnX\subset\mathbb{C}^n be a pure dd-dimensional entire complex analytic subset. Suppose that there exists a sequence T={tj}jNT=\{t_j\}_{j\in\mathbb{N}} of real positive numbers such that tj+t_j\to +\infty and E=CT(X)E=C_{\infty}^T(X) is a dd-dimensional complex linear subspace of Cn\mathbb{C}^n. Here, CT(X)C_{\infty}^T(X) denotes the tangent cone at infinity of XX with respect to TT, and XX is LNE at infinity when its inner and outer distances are uniformly comparable outside a compact set. The affine-linearity conjecture. If XX is LNE at infinity, then XX is an affine linear subspace of Cn\mathbb{C}^n. This extends the preceding result for Lipschitz regularity at infinity, which gives affine linearity under stronger assumptions; the conjecture concerns the corresponding conclusion under LNE at infinity.
