On the Periods of Periodic Motions in Autonomous Systems
Ukrainian Mathematical Journal, 2001Here, the author establishes lower bounds on the periods of periodic solutions to the autonomous system \(\dot x=f(x)\) determined in a partially ordered Banach space \( \langle X,\|\cdot\|,\preceq\rangle\). It is assumed that the mapping \(f:X\mapsto X\) satisfies the condition \({\mathbf m}(f(x_1)-f(x_2))\preceq_E L{\mathbf m}(x_1-x_2)\) for all ...

The period of production is, or purports to be, a measure of aggregate capital per head. More specifically, it is a theoretical concept which tries to measure an economy’s (heterogeneous) capital stock per head in (homogeneous) units of time.

PERIODIC AND QUASI-PERIODIC LAGUERRE TILINGS
International Journal of Modern Physics B, 1993The Laguerre construction extends and unifies the notions of Voronoi (or Dirichlet) and Delaunay complex. It is shown how the standard projection formalism for the generation of quasi-periodic tilings from higher-dimensional periodic “oblique” (or “klotz”) tilings associated to periodic Voronoi and Delaunay complexes also applies more generally to ...

Periodicity and Almost-Periodicity
2006Periodicity and almost-periodicity are phenomena which play an important role in most branches of mathematics and in many other sciences. This is a survey paper1 on my work in this area and on related work. I restrict myself to periodicity questions in combinatorics on words (the main dish), but I start with a periodicity problem from number theory ...
