Research Abstract

We briefly summarize our main results obtained in this research project;
(1) In order to use the quantum gravity to very early universe theory, we developed a method by unifying the quantum gravity with the 2nd law of thermodynamics, i.e.non decreasing of entropy.(M.Ninomiya and H.B.Nielsen at NBI.)
(2) As a new superstring field theory, we proposed a new model and showed that this model reproduces the correct mass spectrum and the Veneziano amplitude.(the same as bove)
(3) In scalar field theory, there appear negative energy solutions. We proposed how totreat them as boson sea.(the same as above)
(4) When applying quantum mechanics to very early universe, we proposed to use a new interpretation of quantum mechanics which is a little similar to recently developed "Transactional interpretation".(the same as above)
(5) H.Kawai worked out in detail the model called type II B matrix theory which is akind of lattice model of superstring. He published many interesting papers.
