Notes Math. Ser. 250, 1-6 (1991). We consider the following population dynamics problem: \[ y_ t+ y_ a+ \mu(a)y- \Delta_ x y= \sum^ n_{i=1} g_ i(a,t)\otimes \delta_{u_ i}\quad\text{in } (0,A)\times \Omega\times (0,T), \]\[ y(0,x,t)= \int^ A_ 0 b(a)y(a,x,t)da\quad\text{in }\Omega\times (0,T), \]\[ y(a,x,t)=0 \quad\text{in }(0,A)\times \partial \Omega\times (0,T),\quad y(a,x,0)=y_ 0(a,x)\quad\text{in }(0,A)\times\Omega. \] The control variable represents the spatial position of impulses. The biological significance of such problems is obvious if we view the above system as population dynamics in \(\Omega\), where \(\Omega\) is an open and bounded subset of \(R^ N\) having a sufficiently smooth boundary \(\partial\Omega\).For the entire collection see [Zbl 0771.00019].
