Structural Stability in Evolving Flow Fieldse structurally stable singularities are folds, which are lines, and cusps, which are isolated points on the folds . In three dimensions they are fold surfaces, which contain ribs, and the ribs themselves may contain isolated singular points. As the field changes with time these singularities inte抱狗不敢前 发表于 2025-3-30 20:19:04
