Half-Yearly Journal: Publishes research on dynamical systems and geometry, including Random Dynamical Systems, hyperbolic behaviour, complex geometry and Ergodic theory.
Issues up to 2022 co-published with and available at:
In this paper: In this paper generalized vector fields are studied. The notion of left invariant vector fields is extended by the use of top spaces. As a result a new kind of dynamics is extrapolated. By the topolog...
In this paper: We will construct a class of one-dimensional models with unique ground states and two spin variables that have a countable number of extreme limits Gibbs states. The work is a modification and extensi...
In this paper: New results on perturbation of continuum-expansive homeomorphisms on locally connected compact metric spaces are deduced. For a continuum-wise expansive homeomorphism , it is not true that: any small...
In this paper: We consider sets of differential equations with quadratic force terms that have a structure that can be diagrammed on star polygons. These can be seen as complementary equations to the ”well-known rep...
In this paper: Story drift of structure is an important indication of structural damage subjected earthquake excitation. It is thus more reasonable to include base shear and story displacement volume in the assessme...
In this paper: We give a brief introduction to the Berline-Vergne localization formula for the finite-dimensional setting and indicate how the Duistermaat-Heckman formula is derived from it. We consider applications...
In this paper: Field equations in Brans-Dicke scalar-tensor theory of gravitation are obtained with the aid a non-static plane symmetric metric in the presence of massive string source. It is shown that a non-static...
In this paper: We study the quantum cosmology of a stringlike toy model. We show that fluctuations of the third-quantized universe field become exponentially large as cosmic scale factor approaches zero, and in the...
