タイトル：Studies on mathematics and computer science and their applications
概要：We introduce how research on mathematics or computer science is carried out in companies. We talk about methods of dealing with difficulties in applying theories on multi-objective optimization, control theory, and machine learning to problems in the real world.

タイトル：On harmonic index designs
概要：Abstract: The notion of harmonic index (or simply HI) design was introduced first as a finite set on a sphere in the form extending the notion of usual spherical designs by Bannai-Okuda-T(2015). They studied about a Fisher type inequality and construction for HI spherical design and argued about the non-existence of tight HI spherical designs. While, Zhu-Bannai-Bannai-Ikuta-Kim(2017) reintroduced the notion of HI t-design in symmetric association schemes and they studied about HI t-designs in binary Hamming schemes. At the beginning of this talk, we will overview the Delsarte theory very briefly. Next I will review a harmonic index design for the spherical case and finally talk about results obtained in the Hamming case for arbitrary q following BOT and ZBBIK.
