In this note we introduce a notion of morphism between two hyperbolic iterated function systems. We prove that the graph is attractor an system, giving Closed Graph Theorem, and show how it can be used to approach topological conjugacy problem for

The paper presents in detail a relatively simple implementation method of the hyperbolic tangent function, particularly targeted for FPGAs. research goal proposed was to examine usage approximation ordinary or Chebyshev polynomials function. Several miscellaneous versions have been considered. They differ polynomial degree, number intervals which domain function is divided, etc. Both floating-p...

We explore the link between wealth inequality and macroeconomic volatility in a two-sector neoclassical growth model with heterogeneous agents. The model has a unique aggregate steady state which is independent of the level of inequality. However, whenever preferences do not exhibit hyperbolic absolute risk aversion, wealth heterogeneity may affect the volatility of output. In particular, we sh...
