| Research Abstract |
A linear operator on a Hilbert space can be regarded as an infinite-dimensional matrix. An inequality for selfadjoint bounded linear operators is a generalization of one for real numbers. An inequality for real numbers does not always hold for operators because of their noncommutativity. In this research, we developed new operator inequalities by using computers. We also show new results in related fields by applying them.
