利用经典的膨胀法和法锥变形法,给出了构造李群样的自然和一般的方法。我们的构造似乎恢复了指标论中涉及的许多已知构造。所得到的变形和爆破群样得到了C^*$-代数的若干扩展和满指标问题。我们计算相应的k -理论映射。最后,一个流形在李群的物体空间中以横向的方式膨胀,导致了一个微积分,非常类似于有边界流形的Boutet de Monvel微积分。
We present natural and general ways of building Lie groupoids, by using the classical procedures of blowups and of deformations to the normal cone. Our constructions are seen to recover many known ones involved in index theory. The deformation and blowup groupoids obtained give rise to several extensions of $C^*$-algebras and to full index problems. We compute the corresponding K-theory maps. Finally, the blowup of a manifold sitting in a transverse way in the space of objects of a Lie groupoid leads to a calculus, quite similar to the Boutet de Monvel calculus for manifolds with boundary.
