Let $x$ and $y$ be two distinct vertices in a connected graph $G$. The $x,y$-location of a vertex $w$ is the ordered pair of distances from $w$ to $x$ and $y$, that is, the ordered pair $(d(x,w), d(y,w))$. A set of vertices $W$ in $G$ is $x,y$-located if any two vertices in $W$ h
Nonlinear Sigma Models in (1 + 2)-Dimensions and An Infinite Number of Conserved Currents
We treat in this paper non-linear sigma models such as CP -model, QP -model and etc, in 1 + 2 dimensions. For submodels of such ones we definitely construct an infinite number of nontrivial conserved currents. Our result is a generalization of that of authors (Alvarez, Ferreira a
N = 2 Chiral Supergravity in ( 10 + 2 ) - Dimensions As Consistent Background for Super ( 2 + 2 ) - Brane
We present a theory of N = 2 chiral supergravity in (10 + 2)-dimensions. This formulation is similar to N = 1 supergravity presented recently using null-vectors in 12D. In order to see the consistency of this theory, we perform a simple dimensional reduction to ten-dimensions, re

A pr 2 00 7 Continuous interfaces with disorder : Even strong pinning is too weak in 2 dimensions
We consider statistical mechanics models of continuous height effective interfaces in the presence of a delta-pinning of strength ε at height zero. There is a detailed mathematical understanding of the depinning transition in 2 dimensions without disorder. Then the variance of th

We give in this paper some formulas which are useful in the construction of nontrivial conserved currents for submodels of CP -model or QP -model in (1 + 2) dimensions. These are full generalization of our results in the previous paper (hep-th 9802105). In the previous paper [1],
Supersymmetric Yang-Mills Equations in 10+2 Dimensions
We present a model for supersymmetric Yang-Mills theory in 10+2 dimensions. Our construction uses a constant null vector, and leads to a consistent set of field equations and constraints. The model is invariant under generalized translations and an extra gauge transformation. Ord
Space - Time Supersymmetry of Extended Fermionic Strings in 2 + 2 Dimensions Sergei
The N = 2 fermionic string theory is revisited in light of its recently proposed equivalence to the non-compact N = 4 fermionic string model. The issues of spacetime Lorentz covariance and supersymmetry for the BRST quantized N = 2 strings living in uncompactified 2+2 dimensions

The derivation procedure of exact ground-states for the periodic Anderson model (PAM) in restricted regions of the parameter space and D = 2 dimensions using plaquette operators is presented in detail. Using this procedure, we are reporting for the first time exact ground-states

I discuss in this talk a bosonization approach recently developed in refs.[1]-[7]. It leads to the (exact) bosonization rule for fermion currents in d ≥ 2 dimensions and also provides a systematic way of constructing the bosonic action in different regimes. Talk delivered at Tren
