Recently, the problem of are the basis of the space of piecewise polynomial functions on a grid representing functions on shapes has also been considered in the geometry and the physical solution of a simulation problem on this isogeometric analysis, using the same basis functions to describe both geometry. In this talk, we will consider spline functions over topological these spline spaces, in particular to analyse their dimension and to manifolds with arbitrary topology. We describe algebraic-geometric techniques which can be used advantageously to get a better insight on construct basis. Examples including splines over triangular meshes or T-meshes, in dimension 2 and 3 will be detailed. 简历：法国国家信息与自动化研究所Bernard MOURRAIN教授长期从事在几何造型、计算机辅助几何、计算符号代数等方向的研究。计算数学领域Journal of Symbolic Computation、SIAM Journal on Applied Algebra and Geometry编委成员、计算几何领Theoretical Computer Science, Computer Aided Geometric Design等受邀编辑。多个计算几何领域国际核心期刊，如Applicable Algebra in Engineering Communication and Computing, Discrete Applied Mathematics, Theoretical Computer Science, Computer Aided Geometric Design, Computer Aided Design, Math.
