Haldane limits via Lagrangian embeddings
In the present paper we revisit the so-called Haldane limit, i.e. a particular continuum limit, which leads from a spin chain to a sigma model. We use the coherent state formulation of the path integral to reduce the problem to a semiclassical one, which leads us to the observation that the Haldane limit is closely related to a Lagrangian embedding into the classical phase space of the spin cha...
متن کاملHeavy Traffic Limits via Brownian Embeddings
For the GI0GI01 queue we show that the scaled queue size converges to reflected Brownian motion in a critical queue and converges to reflected Brownian motion with drift for a sequence of subcritical queuing models that approach a critical model+ Instead of invoking the topological argument of the usual continuousmapping approach, we give a probabilistic argument using Skorokhod embeddings in B...
متن کاملNovikov-symplectic Cohomology and Exact Lagrangian Embeddings
We prove that if N is a closed simply connected manifold and j : L →֒ T ∗N is an exact Lagrangian embedding, then H2(N) → H2(L) is injective and the image of π2(L) → π2(N) has finite index. Viterbo proved that there is a transfer map on free loopspaces H∗(L0N) → H∗(L0L) which commutes under the inclusion of constant loops with the ordinary transfer map H∗(N) → H∗(L). This commutative diagram sti...
متن کاملMean Curvature Flow and Lagrangian Embeddings
In this note we provide examples of compact embedded lagrangians in Cn for any n ≥ 2 that under mean curvature flow develop singularities in finite time. When n is odd the lagrangians can be taken to be orientable. By gluing these lagrangians onto a special lagrangian embedding L we provide examples of compact embedded lagrangians in a Calabi-Yau manifold that under mean curvature flow develop ...
متن کاملLinear embeddings of graphs and graph limits
Many real-life networks can be modelled by stochastic processes with a spatial embedding. In such processes, the link probability decreases with distance. Using the theory of graph limits, we show how to recognize graph sequences produced by random graph processes with a linear embedding (a natural embedding into R). We define an operator Γ which applies to graph limits, which assumes the value...
