31 p, 417.2 KB Uniform methods to stablish Poincaré type linearization theorems / Wu, Hao (Southeast University. Department of Mathematics (Nanjing, Xina))
We find a uniform method to establish Poincaré type linearization theorems for regular systems including classical autonomous, random and almost periodic ones via modified majorant norm methods.

36 p, 338.1 KB Topological and polynomial invariants, moduli spaces, in classification problems of polynomial vector fields / Schlomiuk, Dana (Université de Montréal. Département de Mathématiques et de Statistique)
We describe the origin and evolution of ideas on topological and polynomial invariants and their interaction, in problems of classification of polynomial vector fields. The concept of moduli space is discussed in the last section and we indicate its value in understanding the dynamics of families of such systems. [...]

7 p, 251.2 KB Finding Hamiltonian isochronous centers by non-canonical transformations / Sabatini, Marco (Universita di Trento. Dipartimento di Matematica)
Starting from a class of isochronous Hamiltonian centers, we produce a new class of Hamiltonian isochronous centers by using non-canonical transformations.

32 p, 432.6 KB A survey on stably dissipative Lotka-Volterra systems with an application to infinite dimensional Volterra equations / Oliva, Waldyr M. (Center for Mathematical Analysis, Geometry and Dynamical Systems (Lisboa, Portugal))
For stably dissipative Lotka{Volterra equations the dynamics on the attractor are Hamiltonian and we argue that complex dynamics can occur. We also present examples and properties of some infinite dimensional Volterra systems with applications related with stably dissipative Lotka-Volterra equations. [...]

42 p, 5.2 MB Invariant tori in the lunar problem / Meyer, Kenneth R. (University of Cincinnati. Department of Mathematical Sciences) ; Palacian, Jesus F. (Universidad Pública de Navarra. Departamento de Ingeniería Matemática e Informática) ; Yanguas, Patricia (Universidad Pública de Navarra. Departamento de Ingeniería Matemática e Informática)
Theorems on the existence of invariant KAM tori are established for perturbations of Hamiltonian systems which are circle bundle ows. By averaging the perturbation over the bundle ow one obtains a Hamiltonian system on the orbit (quotient) space by a classical theorem of Reeb. [...]

20 p, 2.9 MB Integrable systems on S3 / Martínez-Alfaro, José (Universitat de València. Departament de Matemàtiques) ; Oliveira, Regilene (Universidade de São Paulo. Instituto de Ciências Matemáticas e de Computação)
We classify the links of basic periodic orbits of integrable vector fields on S3 generalizing results on two degree of freedom Hamiltonian systems. We also study the case of completely integrable systems and define invariants for the two classes of vector fields.

23 p, 585.6 KB Delayed logistic population models revisited / Liz, Eduardo (Universidade de Vigo. Departamento de Matemática Aplicada II)
We discuss the global dynamics of some logistic models governed by delay-differential equations. We focus on models of exploited populations, and study the changes in the dynamics as the harvesting effort is increased. [...]

18 p, 341.2 KB Complex length and persistence of limit cycles in a neighborhood of a hyperbolic polycycle / Ilyashenko, Yu (Cornell University)
Complex limit cycle located in a neighborhood of a hyperbolic polycycle can not vanish under a small deformation that preserves the characteristic values of the vertexes of the polycycle. The cycles either change holomorphically under the change of the parameter, or come to the boundary of the fixed neighborhood of the polycycle. [...]

We consider an outer billiard around a Reulaux triangle. We prove the existence of infinitely many periodic points accumulating at infinity. To do so we con- struct a return map from a strip into itself and we study its properties. [...]

Let X be a germ of holomorphic vector field at 0 2 Cn and let E be a linear subspace of Cn which is invariant for the linear part of X at 0. We give a suficient condition that imply the existence of a non-singular invariant manifold tangent to E at 0. [...]

Let F = (F1, F2, F3): R3 → R3 be a C∞ local diffeomorphism. We prove that each of the following conditions are sufficient to the global injectivity of F: A) The foliations FFi made up by the connected components of the level surfaces Fi = constant, consist of leaves without half-Reeb components induced by Fj , j ∈ {1, 2, 3} \ {i}, for i ∈ {1, 2, 3}.
