摘要翻译:
本文研究了在由非高斯Ornstein-Uhlenbeck过程驱动的具有随机系数的Black-Scholes金融市场上交易的投资者的最优投资和消费问题。我们假设agent基于幂效用函数进行投资和消费决策。应用通常的变量分离方法,我们面临着求解一个非线性(半线性)一阶偏积分微分方程的问题。通过Feynman-Kac表示导出了一个候选解。利用定义在适当函数空间中的算子的性质,证明了解的唯一性和光滑性。应用一个经典的验证定理来验证最优性。

英文摘要:
In this paper, we investigate an optimal investment and consumption problem for an investor who trades in a Black--Scholes financial market with stochastic coefficients driven by a non-Gaussian Ornstein--Uhlenbeck process. We assume that an agent makes investment and consumption decisions based on a power utility function. By applying the usual separation method in the variables, we are faced with the problem of solving a nonlinear (semilinear) first-order partial integro-differential equation. A candidate solution is derived via the Feynman--Kac representation. By using the properties of an operator defined in a suitable function space, we prove uniqueness and smoothness of the solution. Optimality is verified by applying a classical verification theorem.
