地点：齐云楼525报告厅

摘要；Finsler geometry is a natural generalization of Riemannian geometry with the latter as a special case. The study of Finsler geometry may throw new light to the modern physics. In this talk, I will introduce basic concepts of Finsler geometry, such as metric, connection, curvature etc. Then, I will discuss the classification of Randers space (a special case of Finsler geometry), which is a milestone of the researches on Finsler geometry. Symmetry plays an important role in fundamental physics. I will discuss the symmetry of Finsler space by using the isometric group. Einstein first give a geometric description of gravity, i.e. the general relativity. The special Finslerian generalization of the Reissner-Nordstr?m solutions will be discussed. At last, I will introduce “peculiar” properties of Finsler geometry and obstructions in constructing gravitational field equations in general Finsler spacetime.
