Asymmetric Competition

Pairwise invasibility plots in the age-logistic Kisdi example show mutual invasibility and no apparent long-time TSS convergence. The extinction equation in the age-logistic Kisdi example must be solved numerically. In the age-logistic Kisdi example, equilibrium total mass is unique under the same R0 condition but not explicitly available. The competition kernel strongly influences whether convergence, mutual invasibility, or branching occurs. A version of Example 1 replaces logistic competition with an age-logistic Kisdi asymmetric competition kernel.
