In this paper, we consider the following curvature equation Δ + eᵘ = 4π ((₀ − 1)δ₀ + (₁−1)δ₁ + ∑ⁿ⁺ᵐⱼ₌₁(′ⱼ − 1)δₜⱼ)in ℝ², () = −2(1+∞)ln|| + O(1) as || → ∞, where ₀, ₁, ∞, and ′ⱼ are positive non-integers for 1 ≤ j ≤ , while ′ⱼ ∈ ℕ≥₂ are integers for + 1 ≤ j ≤ + . Geometrically, a solution gives r...
