1. 1. Stringed along or caught in a loop? : Philosophical reflections on modern quantum gravity research

   Författare :Keizo Matsubara; Lars-Göran Johansson; Holger Lyre; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; quantum gravity; string theory; loop quantum gravity; philosophy of physics; philosophy of science; scientific realism; structural realism; multiverse; thought experiments; Theoretical Philosophy; Teoretisk filosofi;

   Sammanfattning : A number of philosophical questions, all connected to modern research in quantum gravity, are discussed in this dissertation.The goal of research in quantum gravity is to find a quantum theory for gravitation; the other fundamental forces are already understood in terms of quantum physics.

3. 2. Strings, Conformal Field Theory and Noncommutative Geometry

   Författare :Keizo Matsubara; Anton Alekseev; Edwin Langmann; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Theoretical physics; String theory; Conformal field theory; Noncommutative geometry; Star-products; Teoretisk fysik; Physics; Fysik;

   Sammanfattning : This thesis describes some aspects of noncommutative geometry and conformal field theory. The motivation for the investigations made comes to a large extent from string theory. This theory is today considered to be the most promising way to find a solution to the problem of unifying the four fundamental interactions in one single theory. LÄS MER
