SPATIAL PATTERNS IN POPULATIONS WITH TWO AGE GROUPS: SPATIAL-TEMPORAL CHAOS, CHIMERS, AND SOLITARY STATES

M.P. Kulakov

Аннотация


The article studies the conditions for the emergence of various types of inhomogeneous spatial distribution that arise in the model of populations with two age groups living in an extended two-dimensional area. The author proposes several quantitative indicators to identify the regular (clusters of synchronous populations in the form of spots, stripes or labyrinths) and the irregular (chimeras, solitary states and space-time chaos) spatial structures.
