- Title: QMC designs on the sphere with determinantal point processes
- Abstract: The concept of a QMC(Quasi-Monte Carlo) design sequence was introduced by Brauchart et al (2014). In this talk we give a probabilistic generation of a sequence of QMC designs by using determinantal point processes (DPPs), which are used in a fermion model in quantum mechanics and also studied in probability theory. We show that spherical ensembles and harmonic ensembles, which are the typical types of DPPs on the sphere, give on average faster convergent sequences for Sobolev space on the sphere.

- Title: On the zeros of certain cusp forms related to the Eisenstein series for the Fricke groups of level 2 and 3.
- Abstract: The location of the zeros of Eisenstein series has been considered for a long time. It is known that the zeros of Eisenstein series for SL(2,Z) in the standard fundamental domain lie on the lower arc of it. In this talk, we will present several results for the location of the zeros of certain cusp forms related to the Eisenstein series for the Fricke groups of level 2 and 3.

- Title: Some properties of highly-regular graphs
- Abstract: Classically, highly-regular graphs have been studied as a generalization of strongly-regular graphs. However, highly-regular graphs can also be regarded as a generalization of distance-regular graphs. From this view point, we study combinatorial and spectral aspects of highly-regular graphs. In this talk, as combinatorial results, we give two constructions of highly-regular graphs and some properties of CAM (collapsed adjacency matrix) of highly-regular graphs. Furthermore, we show that highly-regular graphs are spectrally-regular graphs.
