This work represents a first step towards the simulation of the
motion of water in a complex hydrodynamic configuration, such as
a channel network or a river delta, by means of a suitable
“combination” of different mathematical
models. In this framework a wide spectrum of space and time scales is involved
due to the presence of physical phenomena of
different nature.
Ideally, moving from a hierarchy of hydrodynamic models, one should solve
throughout the whole domain the most complex model (with...
In this paper we present a new theorem for monotone including iteration methods. The conditions for the operators considered are affine-invariant and no topological properties neither of the linear spaces nor of the operators are used. Furthermore, no inverse-isotony is demanded. As examples we treat some systems of nonlinear ordinary differential equations with two-point boundary conditions.
To find a zero of a maximal monotone operator, an extension of the
Auxiliary Problem Principle to nonsymmetric auxiliary operators is
proposed. The main convergence result supposes a relationship between
the main operator and the nonsymmetric component of the auxiliary
operator. When applied to the particular case of convex-concave
functions, this result implies the convergence of the parallel
version of the Arrow-Hurwicz algorithm under the assumptions of
Lipschitz and partial Dunn properties...
We develop local and semilocal convergence results for Newton's method in order to solve nonlinear equations in a Banach space setting. The results compare favorably to earlier ones utilizing Lipschitz conditions on the second Fréchet derivative of the operators involved. Numerical examples where our new convergence conditions are satisfied but earlier convergence conditions are not satisfied are also reported.
2000 Mathematics Subject Classification: 47H04, 65K10.In this article, we study a general iterative procedure of the following form 0 ∈ f(xk)+F(xk+1), where f is a function and F is a set valued map acting from a Banach space X to a linear normed space Y, for solving generalized equations in the nonsmooth framework. We prove that this method is locally Q-linearly convergent to x* a solution of the generalized equation 0 ∈ f(x)+F(x) if the set-valued map [f(x*)+g(·)−g(x*)+F(·)]−1 is Aubin continuous...
