摘要: 研究一个数学金融学最优投资理论中的抛物型Monge-Ampère方程初值问题: VsVyy+ryVyVyy-θV2y< /sub>=0, Vyy<0, (s,y)∈[0,T)×R; V(T,y)=1-e-λy, y∈R. 建立了其解V=V(s,y)的存在惟一性以及在最优投资问题中的应用.

关键词: 抛物型Monge-Ampère方程, 初值问题, 初值函数无界, 最优投资问题

Abstract: For the initial value problem of a parabolic Monge-Ampère equation: VsVyy+ryVyVyy-θV2y< /sub>=0, Vyy<0, (s,y)∈[0,T)×R; V(T,y)=1-e-λy, y∈R. arisen from optimal investment theory in mathematical finance, the existence an d the uniqueness as well as the application of the solution V=V(s,y) are established.

Key words: parabolic Monge-Ampère equation, initial value problem, unbounded initial value, optimal investment
