Freeness of hyperplane arrangements associated with gain graphs
Daisuke Suyama, Michele Torielli, Shuhei Tsujie
Athanasiadis studied arrangements obtained by adding shifted hyperplanes to the braid arrangement. Similarly, Bailey studied arrangements obtained by adding tilted hyperplanes to t…
The Primitive Derivation and Discrete Integrals
Daisuke Suyama, Masahiko Yoshinaga
The modules of logarithmic derivations for the (extended) Catalan and Shi arrangements associated with root systems are known to be free. However, except for a few cases, explicit…
Signed graphs and the freeness of the Weyl subarrangements of type
Daisuke Suyama, Michele Torielli, Shuhei Tsujie
A Weyl arrangement is the hyperplane arrangement defined by a root system. Arnold and Saito proved that every Weyl arrangement is free. The Weyl subarrangements of type …
Vertex-weighted graphs and freeness of -graphical arrangements
Daisuke Suyama, Shuhei Tsujie
Let be a simple graph of vertices with edge set . The graphical arrangement consists of hyperplanes $ \{x_{i}-x_…
