... First of all I would like to mention about the vanishing cohomology associated to the Milnor fibre of the isolated hypersurface singularity. We review the results on the Milnor number (local and global) by Kouchnirenko (Inventiones math. 32, No1 (1976), 1-32) and then roughly sketch the formula of Hodge numbers given by Danilov (FAA, 13, No.2(1979),32-47). ... The Hodge structure of the cohomology of an affine hypersurface in an algebraic torus will be discussed. ...

. The UNIX file system is organised as a hierarchy of directories starting from a single directory called root which is represented by a / (slash). Imagine it as being similar to the root system of a plant or as an inverted tree structure. Immediately below the root directory are several system directories that contain information required by the operating system. The file holding the UNIX kernel is also here. UNIX system directories .
