GR in a Nutshell
... The standard choice for a connection in standard GR is the LeviCivita connection, sometimes called “Christoffel symbols.” We get this connection if we start with a metric and assume the connection is torsion-free (and also “metric-compatible”). Now we are supposing the connection might not be torsio ...

Langevin Equation and Thermodynamics
... Our question is, then, how Langevin dynamics is related to the first and second law of equilibrium thermodynamics and also to non-equilibrium thermodynamics. There might be a skepticism that a Langevin equation, or especially 'Y~~ term, describes only irreversible processes. In fact, if we multiply ...

Lorentz violating field theories and nonperturbative physics
... It is possible to re-express resulting field theory in terms of mSME, by use of the Seiberg-Witten map. It expresses the non-commutative fields in terms of ordinary gauge fields. For non-commutative QED this yields the following Lorentzviolating expression, at lowest nontrivial order in 1/ΛNC: Seib ...

Probability in the Many-Worlds Interpretation of Quantum Mechanics

From this it follows that Bob should assign probability pyes = 13 for all states which can be obtained from (2) through actions at regions which are space-lik ...
