タイトル: Implicit differential equations and vector fields with non-isolated singular points

アブストラクト:
In this talk, I am planning to explain how vector fields with non-isolated singular points appear and how their typical phase portraits look like. A natural source of vector fields whose singular points fill a submanifold of codimension two is multidimensional Implicit Differential Equations (i.e., systems of ordinary differential equations not solvable for the derivatives). I am planning to give a survey of the main results in this subject and formulate some open problems.

なお，同日１７：００から幾何学コロキウム：On singularities of simple waves（Dmitry Tunitsky氏，V.A. Trapeznikov Institute of Control Sciences of Russian Academy of Sciences）が開催されます．
