Аннотация: We consider quadratic operators, which map the $n$–dimensional simplex of idempotent measures into itself. We introduce the concept of Volterra quadratic operator on the simplex of idempotent measures and provide some general properties of such operators.
We also consdier a special Volterra quadratic operator and provide a comprehensive analysis of the dynamical system generated by this operator. Moreover, the dynamical systems generated by general Volterra operators defined on 2 and 3–dimensional simplices of idempotent measures are studied. For each case, we find fixed points and limits of trajectories.

Ключевые слова: quadratic operator, Volterra operator, simplex, idempotent measure, fixed point, trajectory, dynamical system, attracting, repelling.
