Title：

The 2nd higher direct image from the Kummer log flat topology to the fppf topology

Abstract：

In this talk, we introduce Kato's Kummer log flat topology on the category of fs log schemes, and discuss the 1st and the 2nd higher direct images from the Kummer log flat topology to the fppf topology. As an example we compute the 1st and the 2nd Kummer log flat cohomology with coefficients in the multiplicative group over some standard log traits.

    AbstractDeep convolutional networks have proved to be extremely powerful in image analysis. However.they tend to be biased toward local features such as texture and often fail to capture the globalstructure of image and volume data. Persistent homology (PH), a tool from the emerging field oftopological data analysis, has been successfully used to detect global characteristics of data thatare ov...

  • 真人百家le威尼斯人:Methods of Algebraic Topology in Graph Theory

    IntroductionCurrently the problem of transferring results of algebraic topology to discrete objects and, in particular, to various categories of digraphs and graphs, is widely investigated. The main technical tools are given by the homotopy theory and various homology theories. We present the basic methods of algebraic topology in graph theory and describe relations between continious and discr...
