Bounded shortening in Coxeter complexes and buildings.

We prove that the standard generating set for a Coxeter group of finite rank satisfies "falsification by a fellow traveller property" in the sense of W. Neumann and M. Shapiro. In particular this implies that the geodesic words in standard generators form a regular language. Similar property established for buildings and this implies rationality of growth series for certain groups acting on buildings.

Спинорные духи, теневые электроны и мультиверс Дойча.

In this article the new solution of the Einstein-Dirac's equations is presented. There are ghost spinors, i.e. the stress-energy tensor equal to zero and the current of these fields is non-zero vector. Last the ghost neutrinos was found. These spinors and shadow particles of Deutsch are identified. And in result the ghost spinors have a phisical interpretation and shadow electrons as another shadow particles the field equations are got.

Мульти-агентная модель импульсного влияния на процесс гендерного взаимодействия в обществе.

In the paper the simulation model of gender contact of agents in artificial society is presented . We are studying the process of the male's and female's interaction based on gender relations. The females radiate the charm pulses. Responding to these pulses, the males choose a female. The computer models were realized on SWARM. Under the computer simulation with various initial data, we reveal three types of agent interaction.

Гендер как «интрига»: возможности компьютерного моделирования в исследовании гендерных систем.

The purpose of this paper was to use the possibilities of computer simulation for investigation of gender systems. Defining the gender as an intrigue allows easy to proceed to constructing the model of gender interaction in society. Submersion in world of artificial gender relations allows to understand real relations. Two simulation models of gender interactions are considered.
