Impulsive release in mathematic
WitrynaView history In classical mechanics, impulse (symbolized by J or Imp) is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector quantity. Impulse applied to an object produces an equivalent vector change in its linear momentum, also in the resultant direction. Mathematical models have been published to investigated the effect of impulsive releases of sterile mosquitoes on mosquito-borne disease transmissions [6, 28,29,30,31,32,33,34,35]. Yu and Li obtained the existence and uniqueness of a periodic solution based on two switching subpopulations. Zobacz więcej Let \omega (t)=(x_1(t),x_2(t),y(t)) be any solution of system (1). Then the wild-mosquito-eradication periodic solution (0,0,y^*(t)) is globally asymptotically stable provided R_0<1,where and \theta =\displaystyle … Zobacz więcej If R_0>1 holds, then the wild mosquitoes are uniformly persistent, which implies there exists a positive constant \varsigma such that the solution (x_1(t),x_2(t),y(t)) of system (1) satisfies \displaystyle \liminf _{t\rightarrow … Zobacz więcej In the first case, we will give the proof of local stability of the wild-mosquito-eradication periodic solution. The local stability of the wild-mosquito-eradication periodic solution … Zobacz więcej If no dispersal happens in each patch, then wild mosquitoes will become extinct for R_{01}<0 and R_{02}<0, where R_{01}=b_1\theta … Zobacz więcej

Often it is important to find the response to an impulse, and then we use the delta function in place of f(t). The solution to Lx = δ(t) is called the impulse response.
