Spatial data model is formalized according to partial order relationship , equivalence relationship and simplicial complex theory . a formalizing two - tuple ( m , f ) multi - resolution spatial data model is presented . based on the jarno peschie algorithms , an improved algorithm of road network map generalization is developed
应用偏序关系、等价关系和单纯复形理论，初步研究了多分辨率空间数据模型形式化表达方法，提出了一个二元组形式化多分辨率空间数据模型。
In section 3 , we show that when i is a squarefree stable ideal , shiftij ( i ) and i have the same graded betti numbers , projective dimension and regularity , then ic and i have the same graded betti numbers , projective dimension and regularity . at last we apply the results we obtained to simplicial complexes
在第三节中证明了当i为无平方稳定理想时， shiftij ( i )与i的分次betti数、投射维数和正则度相同，从而i ~ c与i的分次betti数、投射维数和正则度相同，最后将所得结论推广到单纯复形上。
