AI 中文摘要
我们给出用于计算阿米巴轮廓奇点的显式实代数方程,将对数临界轨迹的退化与不同临界提升的重合分离开来。对于平面曲线,这产生了检测节点、尖点和多分支的实用系统。我们还表明,即使对于格三角形和平行四边形,最大稀疏性也不会使轮廓奇点最大化。
英文摘要
We give explicit real-algebraic equations for computing the singularities of amoeba contours, separating degeneracies of the logarithmic critical locus from coincidences of distinct critical lifts. For plane curves, this yields practical systems detecting nodes, cusps, and multiple branches. We also show that maximal sparsity does not maximize contour singularities, even for lattice triangles and parallelograms.
