SUMMARY:Age of Information Processes under Strongly Mixing Communication
DESCRIPTION:The decentralized nature of multi-agent systems requires
 continuous data\nexchange to achieve global objectives. In such
 scenarios\,\nAge-of-Information (AoI) has become an important metric for
 the\nfreshness of communicated data. The study of AoI consequently has
 to\ntake into account the dependencies that communication systems
 exhibit:\nThe process describing the success or failure of communication is
 highly\ncorrelated when these attempts are ``close'' in some domain. To
 study\nAoI in such scenarios\, I will introduce fundamental AoI
 processes\n$\\Delta(n)$\, expressing the discrete-time since the last
 update from a\nsource at a monitor: If during time slot $n$ the monitor
 receives a\nstatus update from the source (event $A(n)$)\, then
 $\\Delta(n+1)$ is\nreset to one\, otherwise\, $\\Delta(n)$ grows linearly
 in time. This AoI\nprocess is a special random walk with resets. The event
 process $A(n)$\nmay be non-stationary and we assume that its temporal
 dependencies\ndecay\, described by $\\alpha$-mixing. With this\, moment
 bounds and growth\nbounds follow for the resulting AoI process as a
 function of the mixing\nrate of $A(n)$. In addition\, the AoI process
 $\\Delta(n)$ is itself\n$\\alpha$-mixing. I will then discuss how the
 fundamental AoI processes\npresented can be used to model more complex AoI
 structures that do not\nnecessarily reset to one when information is
 updated and where multiple\nsources may lead to AoI at a monitor.
