| Research Abstract |
When we integrate some polynomial function on a n-dimensional sphere, if the integrand polynomial is at most degree 2, we clarified the condition on an optimal Euclidean design with two concentric spheres. Conditions on an optimal Euclidean design is given by (i) the ratio the radius of two spheres, (ii) the number of points chosen from each sphere and (iii) the configuration of points for each concentric sphere. We obtained such conditions that a cubature formula is optimal and gave constructions of Euclidean designs which satisfy the conditions. These results were accepted as papers for Sankha Indian Journal of Statistics, etc.
Moreover, we introduced a notion of mutually orthogonal t-designs (t-MOD) over
the complex number field. We examined some conditions for a t-MOD to be optimal. And we find that t-MOD is equivalent to a quantum jump code.
