The closed string sector can be seen to decouple leaving a theory which contains only open strings [4, 5], unless, as Klebanov and Maldacena have pointed out , one compactiﬁes the theory on a circle along the direction of the electric ﬁeld.
IIA/B, Wound and Wrapped
This could be useful for constructing a duality between matrix string theory on the pp-wave and gauge theory since this background still admits a matrix string description while we have an N = 2 QGT on the gauge side, which makes the duality simpler than if we consider the one of the previous section.
Gauge theory description of compactified pp-waves
It is moreover important to note that we have accounted for all of the scalar chiral primaries in this particular scaling limit of N = 2 QGT, so we really have a oneto-one correspondence between the bosonic supergravity modes on the string side and the scalar chiral primaries on the gauge theory side.
Gauge theory description of compactified pp-waves
He argued that the unstable vacuum is one with a space-ﬁlling “Dbrane” carrying positive energy density. D-branes have been a ma jor sub ject of study in string theory over the last decade. D-branes are higher-dimensional extended ob jects on which open strings can end.
String Field Theory
That means that now we have a single possible string worldsheet, one that ends on the Wilson loop contour at r0 ≤ r ≤ r1 , and ”drops” to r = r1(α), where is turns back.
Gluon scattering in ${\cal N}=4$ Super Yang-Mills at finite temperature
A–twisted sigma model” whose open sector also contains open strings having one end on S 3 and the other on CK : the non–constant instantons associated with their world sheet give a non–trivial contribution to the string amplitude.
Large N dualities and transitions in geometry
We have already seen that for the one charge case (where we had just the string NS1 wrapped on a circle n1 times) we get Smicro = ln[256].
The quantum structure of black holes
For example, if we have some ﬁnite number N of D3-branes sitting on top of each other in ﬂat space, one ﬁnds that the low energy dynamics of the open string excitations can be described by a non-abelian gauge theory.
Quark Soup al dente: Applied Superstring Theory
Due to the property of “T-duality” (which relates the compactiﬁcation on radius R with the one of inverse radius 1/R and is discussed in Section 6.3), strings in thermal equilibrium have a maximum temperature TH , the Hagedorn temperature.
Primordial Fluctuations in String Cosmology
Note that the only attributes whose domains are character strings can have lengths more than one word and the ordering assumed on such domains is the lexicographic ordering. Now suppose a bucket overflow necessitates the refinement of the linear scale on some attribute i, by splitting an interval [V1..V2].
Using Grid Files for a Relational Database Management System
One explains the possibility that strings can end on a hyper-surface by considering the boundary conditions that the coordinate ﬁelds of open strings have to satisfy at their endpoints.
Symmetries and interactions in matrix string theory
One might have naively guessed that the formula would involve β instead of β − 1, on the grounds that the entropy of the sequence of names is ∼ βN log N , but this is the rate in a third model where a vertex name is a pair (i, a), where 1 ≤ i ≤ N and a is the random string.
Entropy of Some Models of Sparse Random Graphs With Vertex-Names
Xi is the random variable for the contribution of all strings at Hubble time ti to the velocity perturbation of V , and νi denotes the average number of strings having an effect on V at time ti , i.e. those strings which are within a distance of one Hubble radius of V at time ti (see eq.(18)).
Statistics of Peculiar Velocities from Cosmic Strings
Such a network is expected to evolve very differently from the standard one, and hence have different cosmological consequences; might they be such as to ‘save’ cosmic strings? Secondly, it is interesting to focus on the loop network alone (which, we believe, has not been done).
