This quantity includes 23 articles on algebraic research of differential equations and similar subject matters, such a lot of that have been provided as papers on the foreign convention "Algebraic research of Differential Equations – from Microlocal research to Exponential Asymptotics" at Kyoto college in 2005.

Microlocal research and exponential asymptotics are in detail hooked up and supply strong instruments which were utilized to linear and non-linear differential equations in addition to many similar fields similar to genuine and complicated research, necessary transforms, spectral idea, inverse difficulties, integrable platforms, and mathematical physics. The articles contained right here current many new effects and concepts.

This quantity is devoted to Professor Takahiro Kawai, who's one of many creators of microlocal research and who brought the means of microlocal research into exponential asymptotics. This commitment is made at the get together of Professor Kawai's sixtieth birthday as a token of deep appreciation of the real contributions he has made to the sector. Introductory notes at the medical works of Professor Kawai also are included.

**Analysis of SAR Data of the Polar Oceans: Recent Advances**

This booklet experiences contemporary advances within the use of SAR imagery for operational functions and for aiding technology investigations of the polar oceans. the $64000 parameters which might be extracted from spaceborne SAR imagery are mentioned. Algorithms utilized in such analyses are defined and knowledge platforms utilized in generating the ocean ice items are supplied.

Fk−1 . Let V (x0 , f0 , . . , fk ) denote the germ at x0 of the analytic variety of common zeros of f0 , f1 , . . , fk . Since Ox0 is a Cohen-Macaulay ring, we have the following Theorem 1. Let l be a non-negative integer smaller than n and f0 , f1 , . . , fl be elements in Ox0 vanishing at x0 . Then the following three conditions are equivalent: 1. The sequence f0 , f1 , . . , fl is a regular sequence at x0 . 2. For each k = 0, 1, . . , l, the dimension of V (x0 , f0 , . . , fk ) is equal to n − k − 1.
