Explosive fragmentation of thin ceramic tube using pulsed power
Hiroaki Katsuragi, Satoshi Ihara, Haruo Honjo
This study experimentally examined the explosive fragmentation of thin ceramic tubes using pulsed power. A thin ceramic tube was threaded on a thin copper wire, and high voltage wa…
Stanley--Reisner rings with large multiplicities are Cohen--Macaulay
Naoki Terai, Ken-ichi Yoshida
We prove that certain class of Stanley--Reisner rings having sufficiently large multiplicities are Cohen--Macaulay using Alexander duality.
On the radical of a monomial ideal
Juergen Herzog, Yukihide Takayama, Naoki Terai
Algebraic and combinatorial properties of a monomial ideal and its radical are compared.
A family of Schottky groups arising from the hypergeometric equation
Takashi Ichikawa, Masaaki Yoshida
We study a complex 3-dimensional family of classical Schottky groups of genus 2 as monodromy groups of the hypergeometric equation. We find non-trivial loops in the deformation spa…
AAC analysis of polarized parton distributions with uncertainties
M. Hirai, S. Kumano, N. Saito
We report recent studies of the Asymmetry Analysis Collaboration (AAC) on polarized parton distribution functions (PDFs). Using the data on the spin symmetry A_1 in deep inelastic…
