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.

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 ...
