Rees algebras and iterated Jacobian duals
… a new method, namely "iterated'' Jacobian duals, to study the graph of Ψ. This is a generalization of the usual Jacobian duals which are often used to describe the graph of Ψ.</p>

Chiral symmetry breaking transitions in holographic duals
Generalisations of the AdS/CFT Correspondence are used to study chiral symmetry breaking in dual gauge theories. We use the D3/D7 and D3/D5 systems to model both 3+1 and 2+1 dimensional, strongly coupled, gauge theories with quark fields. We show that chiral symmetry breaking is induced by either …

Planar Graphs and their Duals on Cylinder Surfaces
… a new characterization of queue graphs and their duals. We also consider the complexity of deciding whether a graph is a deque graph and prove that it is NP-complete. By introducing a split operation, we obtain the splittable deque and show that it characterizes planarity. For the proof, we devise …

Aspects of transport in strongly correlated systems with gravity duals
… U(1) spontaneous symmetry breaking, and gravity duals of non-relativistic field theories, in which the MS bound is not saturated. Finally, we study the effect of a weak breaking of translational symmetry and we show that the MS bound sets a lower bound on the DC conductivity for a given …

On some spaces related to weak L(p) and their duals
"In Cwikel's paper ""On the dual of Weak $L\sp{p}$"", it is shown that (Weak $L\sp{p})\sp\prime = L(p\sp\prime, 1)\oplus S\sb0\oplus S\sb\infty.$ For non-atomic measure spaces, Cwikel obtains a representation of elements in $S\sb0$ and $S\sb\infty.$ However, we show that this representation is …

Generalized DF spaces
… certain essential properties with the strong duals of Frechet spaces. The class of DF spaces includes not only all such duals, but also every· normed space and many other spaces besides. The definition of a DF space is due to Grothendieck, who derived almost all the important results …

The generalized Tate construction
… next section makes a computation and gives the duals of L(n) = L(n)1. The last part looks ahead, mentioning how this computation could be extended to finding the duals of Steinberg summands in corresponding Thom spectra of negative representations, L(n)-q, and presents an equivariant loopspace …

Aspects of strongly-coupled field theory from gauge-gravity duality
… fundamental representation matter to gravity duals. We present a method for calculating the quasinormal frequencies associated to mesonlike excitations in non-zero temperature gravity duals and apply it to excitations of bosonic and fermionic type. We study the thermal phase transition in a …

p-arithmetic cohomology and p-adic automorphic forms
… For example, we show that the cohomology of (duals of) locally algebraic representations of the local groups at places in *S* can be described in terms of automorphic representations satisfying certain conditions determined by the locally algebraic representation. We show that the cohomology …

Categories of spaces built from local models
… category in which one can glue (the formal duals of) commutative rings along (the formal duals of) distinguished homomorphisms. Traditionally, the ambient category is taken to be the category of locally ringed spaces, but following Grothendieck, one could equally well work in the category of …

Entanglement in gauge/ gravity duality
… gauge theories and the geometry of their gravity duals. In the first, we find that in a certain class of time-dependent states which have a gravity dual in which a black hole forms, the entanglement entropy of large regions grows linearly in time, following the growth of certain time-like slices …

Equivariant quantum cohomology and the geometric Satake equivalence
… resolutions are expected to be symplectic duals of Nakajima quiver varieties, and thus our result is an analogue of (part of) the work of Maulik and Okounkov in the symplectic dual setting.

Sequential Decision-making Under Uncertainty: Novel Methodologies and Applications
… by applying decision rules in Lagrangian duals of the MSMIP. We propose two new bounding techniques based on stagewise and nonanticipative Lagrangian duals. Our proposal requires fewer assumptions than most existing MSMIP methods. Our numerical experiments demonstrate that the LDDR …

Two problems in the theory of curves over fields of positive characteristic
… a full flag of codes, if it is equivalent to its duals, then it is said to have the isometry-dual property. Introducing characterizations of isometry-dual property for one-point AG codes and its preservation after puncturing at some points, some generalizations in different directions will be …

Aspects of SU(2|4) symmetric field theories and the Lin-Maldacena geometries
… theory on R×S². We use the supergravity duals to calculate new instanton amplitudes for the Plane-Wave Matrix Model at strong coupling. Finally, we study a natural coarse-graining of the vacua, and find that the associated geometries are singular. We define an entropy functional that …

Actions of finite dimensional non-commutative, non-cocommutative Hopf algebras on rings
… that are not isomorphic to group rings or their duals. We compute several examples of such actions, and in particular, we prove that there are no actions of nontrivial semisimple Hopf algebras with dimension less than or equal to 15 on polynomial algebras.

Inter-block analysis of incomplete block designs

Holographic view of non-relativistic physics

Discrete light cone quantization (DLCQ) of V= 4 super Yang-Mills theory is an example of such a system with z = 2 scaling …
