Research Abstract |
One result is the research of varieties of power sums with Francesco Zucconi. We discovered a connection between behaviors of rational curves on quintic del Pezzo threefold and the moduli spaces of trigonal even spin curves through varieties of power sums. Our main result in this direction is that we showed the rationality of even spin curves of genus four. Another result is the research of the mirror symmetry and the projective geometry of certain determinantal Calabi-Yau threefolds with Shinobu Hosono.We constructed two types of Calabi-Yau threefolds and showed that they have the same mirror. Moreover, based on this we calculated the BPS numbers of them and interpreted some of them by the projective geometry.
