DEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
متن کاملNonperturbative Superpotentials in String Theory
We describe a class of 4d N=1 compactifications of the SO(32) heterotic/type I string theory which are destabilized by nonperturbatively generated superpotentials. In the type I description, the destabilizing superpotential is generated by a one instanton effect or gaugino condensation in a nonperturbative SU(2) gauge group. The dual, heterotic description involves destabilization due to worlds...

Acknowledgements First and foremost, I would like to thank Philip Candelas for his invaluable help throughout my four years in Oxford. I also owe special thanks to Bogdan Florea, Marcos Mariño and Harald Skarke for stimulating and enjoyable collaborations on the research topics discussed in this thesis. many others for interesting mathematical physics discussions. Many thanks to my parents, who...
متن کاملA New Formulation of String Theory
Quantum string theory is written as integrable analytic geometry on the universal moduli space of Riemann surfaces.

(1.3) L = tr(F ∧ ?F ) + ψ 6Dψ +mψψ, where m ∈ C is a parameter whose phase diagram we’re interested in. Let m denote the mass of the domain wall theory, which is a 3D QCD theory, so m is real. If m is real and negative, there’s a phase transition: for m 0, the low energy theory is believed to be trivial, and for m 0 (m negative of larger magnitude), the low-energy theory is believed to be SU(N)...
