On boundedness and moduli spaces of K-stable Calabi-Yau fibrations over curves
Kenta Hashizume, Masafumi Hattori
We show boundedness of polarized Calabi--Yau fibrations over curves only with fixed volumes of general fibers and Iitaka volumes. As its application, we construct a separated coars…
On the GIT stability of linear systems of hypersurfaces in projective space
Masafumi Hattori, Aline Zanardini
We consider the problem of classifying linear systems of hypersurfaces (of a fixed degree) in some projective space up to projective equivalence via geometric invariant theory (GIT…
Minimizing CM degree and specially K-stable varieties
Masafumi Hattori
We prove that the degree of the CM line bundle for a normal family over a curve with fixed general fibers is strictly minimized if the special fiber is either a smooth projective m…
Minimization of Arakelov K-energy for many cases
Masafumi Hattori, Yuji Odaka
We prove that for various polarized varieties over , which broadly includes K-trivial case, K-ample case, Fano case, minimal models, certain classes of fibra…
On K-stability of Calabi-Yau fibrations
Masafumi Hattori
We show that Calabi-Yau fibrations over curves are uniformly K-stable in an adiabatic sense if and only if the base curves are K-stable in the log-twisted sense. Moreover, we prove…
On fibration stability after Dervan-Sektnan and singularities
Masafumi Hattori
We introduce -stability, a modification of fibration stability of Dervan-Sektnan [12], and show that -semistable fibrations have only semi log canonical…
Material survey for millimeter-wave absorber using 3-D printed mold
T. Otsuka, S. Adachi, M. Hattori +2
Radio absorptive materials (RAMs) are key elements for receivers in the millimeter-wave range. For astronomical applications, cryogenic receivers are widely used to achieve a high-…
A decomposition formula for J-stability and its applications
Masafumi Hattori
For algebro-geometric study of J-stability, a variant of K-stability, we prove a decomposition formula of non-archimedean -energy of -dimensional varieties into …
