Minimal area surfaces in AdS_{n+1} and Wilson loops
The AdS/CFT correspondence relates the expectation value of Wilson loops in N=4 SYM to the area of minimal surfaces in AdS_5 In this paper we consider minimal area surfaces in generic Euclidean AdS_{n+1} using the Pohlmeyer reduction in a similar way ...

New symmetry of intended curved reaches
Background Movement regularities are inherently present in automated goal-directed motions of the primate's arm system. They can provide important signatures of intentional behaviours driven by sensory-motor strategies, but it remains unknown if during ...

Two-point gauge invariant quark Green's functions with polygonal phase factor lines
Polygonal lines are used for the paths of the gluon field phase factors entering in the definition of gauge invariant quark Green's functions. This allows classification of the Green's functions according to the number of segments the polygonal lines ...

Global topological classification of Lotka-Volterra quadratic differential systems
The Lotka-Volterra planar quadratic differential systems have numerous applications but the global study of this class proved to be a challenge difficult to handle.

Some remarks about Mishchenko-Fomenko subalgebras [PDF]
We discuss and compare two different approaches to the notion of Mishchenko--Fomenko subalgebras in Poisson-Lie algebras of finite-dimensional Lie algebras.

Spectral theory and nonlinear problems Théorie spectrale et problèmes non-linéaires [PDF]
We present a Lie algebra theoretical schema leading to integrable systems, based on the Kostant-Kirillov coadjoint action. Many problems on Kostant-Kirillov coadjoint orbits in subalgebras of infinite dimensional Lie algebras (Kac-Moody Lie algebras)

Cubic differential systems with six real invariant straight lines along two directions
Sunt clasi cate sistemele cubice cu exact ¸sase drepte invariante de dou¼a direc¸tii ¸tinându-se cont la enumerare de gradul lor de invarian¸t¼a. Se arat¼a c¼a, din punct de vedere topologic, sunt 11 clase distincte de astfel de sisteme. Pentru ecare dintre aceste clase este construit pe discul Poincaré portretul fazic.

Parallel algorithm for determining motion vectors in ice floe images by matching edge features [PDF]
A parallel algorithm is described to determine motion vectors of ice floes using time sequences of images of the Arctic ocean obtained from the Synthetic Aperture Radar (SAR) instrument flown on-board the SEASAT spacecraft.

An exact prediction of [script N] = 4 supersymmetric Yang–Mills theory for string theory [PDF]
We propose that the expectation value of a circular BPS-Wilson loop in [script N] = 4 supersymmetric Yang–Mills can be calculated exactly, to all orders in a 1/N expansion and to all orders in g2N.
