Wilson loops for triangular contours with circular edges

چکیده
We calculate Wilson loops in lowest order of perturbation theory for triangular contours whose edges are circular arcs. Based on a suitable disentanglement the relations between metrical and conformal parameters contours, result fits perfectly structure predicted by anomalous Ward identity. The remainder function depends generic 4D case three cusp torsion angles. restrictions these angles imposed closing contour discussed detail also cases 3D 2D.

Active Contours without Edges
1 ACTIVE CONTOURS WITHOUT EDGES Chan and Vese [1] proposed an approximation for the MS segmentation model by following the level-set based curve evolution formulation [2, 3]. Level sets provide an implicit contour representation where an evolving curve is represented with the zerolevel line of a level set function (Figure 1). The basic aim of Chan and Vese (CV) model is to partition a given ima...
متن کاملActive contours without edges
We propose a new model for active contours to detect objects in a given image, based on techniques of curve evolution, Mumford-Shah (1989) functional for segmentation and level sets. Our model can detect objects whose boundaries are not necessarily defined by the gradient. We minimize an energy which can be seen as a particular case of the minimal partition problem. In the level set formulation...
متن کاملHolographic Wilson Loops
We show that all half-BPS Wilson loop operators in N = 4 SYM – which are labeled by Young tableaus – have a gravitational dual description in terms of D5-branes or alternatively in terms of D3-branes in AdS5×S. We prove that the insertion of a half-BPS Wilson loop operator in the N = 4 SYM path integral is achieved by integrating out the degrees of freedom on a configuration of bulk D5-branes o...
متن کاملWilson loops as Precursors
There is substantial evidence that string theory on AdS5 × S5 is a holographic theory in which the number of degrees of freedom scales as the area of the boundary in Planck units. Precisely how the theory can describe bulk physics using only surface degrees of freedom is not well understood. A particularly paradoxical situation involves an event deep in the interior of the bulk space. The event...
متن کاملSpecial contact Wilson loops
Wilson loops in N = 4 supersymmetric Yang-Mills theory correspond at strong coupling to extremal surfaces in AdS5. We study a class of extremal surfaces known as special Legendrian submanifolds. The ”hemisphere” corresponding to the circular Wilson loop is an example of a special Legendrian submanifold, and we give another example. We formulate the necessary conditions for the contour on the bo...
