Takuya Ikuta (Kobe Gakuin University)
Title:The Nomura algebra of some type II matrices


Shizuo Kaji (Yamaguchi University)
Title:An invitation to Schubert calculus


Noguchi Kenta (Keio University)
Title:(Minimum genus embeddings of graphs and their characteristics


Keisuke Shiromoto (Kumamoto University)
Title:Codes over rings and matroids
Abstract:
We consider a class of generalizations of matroids, called demi-matroids, which have a duality property.
This talk shall give some fundamental results on demi-matroids including duality theorems, et al., and a construction of demi-matroids from linear codes over finite quasi-Frobenius rings. Then we apply some results on demi-matroids to linear codes over these rings and show duality theorems such as a Wei-type duality of generalized Hamming weights for these codes.


Kohei Matsushita (Kyushu University)
Title:(On characterization of the animation created by interpolation used a transform matrix)
