Is dark energy even allowed in string theory?

Maldacena, N 6 superconformal. I wrote this to try to collect my thoughts, preparing a talk for the Heineman Prize. Often, string theory has been accused of merely providing abstract mathematical results and making too few predictions that can actually be verified in an experiment.

There are also interesting relations to the theory of self-dual fields, anomaly cancellation, and noncommutative geometry. We show polar states are "split" D6-anti-D6 bound states, and that the partition function factorizes accordingly, leading to a refined version of the OSV conjecture.

This result is a significant generalization of the result in [RW03], where polynomial time computability has been shown for a restricted type of hyperbolic Julia sets. In the final section we discuss the issue of whether physical systems could defeat the Church-Turing Thesis.

But with the discovery of the accelerated expansion of the cosmos, the cosmological constant has been reintroduced as dark energy into the current standard model of cosmology. These theoretical considerations undercut a numb On the complexity of real functions by Mark Braverman" Wrase was able to show that the Higgs field also has properties that should actually be forbidden by Vafa's conjecture—and the Higgs field is considered an experimentally proven fact.

In this paper we give an answer to both of these questions, which were the main open problems concerning the computability of polynomial Julia sets. Using this theory of physical oracles, an experimenter performing an experiment can be modelled as a Turing machine governing an oracle that is the experiment.

We show how to construct a specific polynomial with a non-computable Julia set. I wrote this since the AMS requested a response.

He suggested that such "bowl-shaped" fields of positive energy are not possible in string theory. The two-particle state can be written in terms of the incoming 98 O. Jack Copeland - American Behavioral Scientist" We investigate different definitions of the computability and complexity of sets in R k, and establish new connections between these definitions.

For example - I pointed out in that the attractor mechanism of supersymmetric black holes singles out Calabi-Yau varieties with relations to complex multiplication. Working with him has made my learning process a pleasant one. Pufu, and Benjamin R. Effective low energy supergravity theories in string compactification and the computation of nonperturbative stringy effects in effective supergravities.

It was also unk Einstein actually did this to construct a non-expanding universe. This differs from the original conjecture in several aspects.

Nothing known at present rules out the possibility that machines in this class will one day be built, nor that the brain itself is such a machine. We find that the weak topological coupling OSV conjecture can be true at most in a special chamber of the K"ahler cone.

D17Gen. Barry Cooper" Generally, the underlying atomic processes are quite well understood, and with important exceptions captured by mathematics from which it is relatively easy to extract algorithmic content. Potential connections to number theory. In this paper we begin to explore these questions with the help of the philosophy of physics.

These fields have a state of minimal energy—much like an apple lying in a bowl. Timm Wrase of the Vienna University of Technology quickly realized something odd about this conjecture: Starting from a formal definition of a measurement procedure, different approaches to associate a representation with a measurement procedure are studied, and an equivalence class of representations suitable for representing the results of a measurement is defined for each measurement procedure.

For its discovery, the Nobel Prize in Physics was awarded. On the other hand, according to standard cosmology, the universe settled We assume the reader is familiar with our [5]. We apply the concepts developed to show that hyperbolic Julia sets are polynomial time computable.

by Frederik Denef, Michael R. Douglas - I Abstract: We study the computational complexity of the physical problem of finding vacua of string theory which agree with data, such as the cosmological constant, and show that such problems are typically NP hard.
