Extended dynamic mode decomposition with dictionary learning using neural ordinary differential equations

Hiroaki Terao, Sho Shirasaka, Hideyuki Suzuki

Nonlinear phenomena can be analyzed via linear techniques using operator-theoretic approaches. Data-driven method called the extended dynamic mode decomposition (EDMD) and its vari…

On restrictions of Weyl arrangements

Takuro Abe, Hiroaki Terao, Tan Nhat Tran

Let be a Weyl arrangement in an -dimensional Euclidean space. The freeness of restrictions of was first settled by a case-by-case method by Orlik…

Logarithmic vector fields for quasihomogeneous curve configurations in P^2

Hal Schenck, Hiroaki Terao, Masahiko Yoshinaga

Let A be a union of smooth plane curves C_i, such that each singular point of A is quasihomogeneous. We prove that if C is a smooth curve such that each singular point of A U C is…

Free filtrations of affine Weyl arrangements and the ideal-Shi arrangements

Takuro Abe, Hiroaki Terao

In this article we prove that the ideal-Shi arrangements are free central arrangements of hyperplanes satisfying the dual-partition formula. Then it immediately follows that there…

Canonical systems of basic invariants for unitary reflection groups

Norihiro Nakashima, Hiroaki Terao, Shuhei Tsujie

It has been known that there exists a canonical system for every finite real reflection group. The first and the third authors obtained an explicit formula for a canonical system i…

The freeness of ideal subarrangements of Weyl arrangements

Takuro Abe, Mohamed Barakat, Michael Cuntz +2

A Weyl arrangement is the arrangement defined by the root system of a finite Weyl group. When a set of positive roots is an ideal in the root poset, we call the corresponding arran…
