چکیده
It is shown that Einstein-Yang-Mills-dilaton theory has a countable family of static globally regular solutions which are purely magnetic but uncharged. The discrete spectrum of masses of these solutions is bounded from above by the mass of extremal Gibbons-Maeda solution. As follows from linear stability analysis all solutions are unstable.

Saddle points of stringy actions
We show that Einstein-Yang-Mills-dilaton theory has a countable family of static globally regular solutions which are purely magnetic but uncharged. The discrete spectrum of masses of these solutions is bounded from above by the mass of extremal Gibbons-Maeda solution. Linear stability analysis shows that all solutions are unstable. *) On leave of absence from Institute of Physics, Jagellonian ...
متن کاملLocating and Characterizing the Stationary Points of the Extended Rosenbrock Function
Two variants of the extended Rosenbrock function are analyzed in order to find the stationary points. The first variant is shown to possess a single stationary point, the global minimum. The second variant has numerous stationary points for high dimensionality. A previously proposed method is shown to be numerically intractable, requiring arbitrary precision computation in many cases to enumera...
متن کاملStudy of the noise-induced transition and the exploration of the phase space for the Kuramoto–Sivashinsky equation using the minimum action method
Noise-induced transition in the solutions of the Kuramoto–Sivashinsky (K–S) equation is investigated using the minimum action method derived from the large deviation theory. This is then used as a starting point for exploring the configuration space of the K–S equation. The particular example considered here is the transition between a stable fixed point and a stable travelling wave. Five saddl...
متن کاملOn the Convergence of Min/sup Points in Optimal Control Problems
In case f0 and C are convex, a variety of primal/dual numerical methods can be used to find the saddle points of a Lagrangian L associated with this problem [4, 7]. These methods take advantage of the fact that the search for the saddle points of L is unconstrained, or conducted over sets much simpler than C. Furthermore, we can introduce penalties on f0 in a way that regularizes L and makes it...
متن کاملMultiple Contour Finding and Perceptual Grouping as a Set of Energy Minimizing Paths
We address the problem of finding a set of contour curves in an image. We consider the problem of perceptual grouping and contour completion, where the data is a set of points in the image. A new method to find complete curves from a set of contours or edge points is presented. Our approach is an extension of previous work on finding a set of contours as minimal paths between end points using t...
