  • An important problem in conformal geometry is the construction of conformal metrics for which a certain curvature quantity equals a prescribed function, e.g. a constant. In two dimensions, the uniformization theorem assures the existence of a conformal metric with constant Gauss curvature. Moreover, J. Moser [20] proved that for every positive function f on S 2 satisfying f (x) = f (−x) for all x ∈ S 2 there exists a conformal metric on S 2 whose Gauss curvature is equal to f . A natural conformal invariant in dimension four is 1 Q = − (∆R −...

  • [ Team LiB ] Using an Existing Personal Store If you used Outlook previously, you might have an existing personal message store (PST) you'd like to use. But when you create a new profile in Outlook, it doesn't give you the opportunity to choose the message store to use—it creates a new one for you. You must go back into the menu and add your existing PST. Outlook 2003 uses a new message store format that provides Unicode support and can exceed the 2GB limitation found in Outlook 97–2002 format. As a result, you should consider moving or importing the...

  • IN the last Lecture I endeavoured to prove to you that, while, as a general rule, organic beings tend to reproduce their kind, there is in them, also, a constantly recurring tendency to vary--to vary to a greater or to a less extent. Such a variety, I pointed out to you, might arise from causes which we do not understand; we therefore called it spontaneous; and it might come into existence as a definite and marked thing, without any gradations between itself and the form which preceded it. I further pointed out, that such a variety having once arisen, might be perpetuated to some extent,...

  • What is the potential for a divergence in views among civilian and military elites (sometimes referred to as the civil-military gap) to undermine military effectiveness? The authors propose a five-stage analytical framework that encompasses the main areas where a civil-military gap might have an impact. Using an existing

  • We present a new approach to learning a semantic parser (a system that maps natural language sentences into logical form). Unlike previous methods, it exploits an existing syntactic parser to produce disambiguated parse trees that drive the compositional semantic interpretation. The resulting system produces improved results on standard corpora on natural language interfaces for database querying and simulated robot control.

  • Research objective: The thesis is devoted to extend some results on the existence of fixed points in metric spaces to spaces with uniform structure. We also considered the existence of solutions of some classes of integral equations with unbounded deviation, which we can not apply fixed point theorems in metric spaces. The thesis can be a reference for under graduated students, master students and Ph.D students in analysis major in general, and the fixed point theory and applications in particular.

  • An origin of these algorithms is found in the Darwian principles of natural selection (Darwin, 1859). In accordance with these principles, only the fittest individuals can survive in the struggle for existence and reproduce their good characteristics into next generation. As illustrated in Fig. 1, evolutionary algorithms operate with the population of solutions. At first, the solution needs to be defined within an evolutionary algorithm. Usually, this definition cannot be described in the original problemcontext directly....

  • In this chapter we investigate a general optimization problem in a real normed space. For such a problem we present assumptions under which at least one minimal point exists. Moreover, we formulate simple statements on the set of minimal points. Finally the existence theorems obtained are applied to approximation and optimal control problems.
