    "abstract": "This paper investigates a class of generalized inverse mixed variational inequality problems (GIMVIPs), which consist in finding a vector $\\overline{w}\\in \\R^d$ such that \\[ F(\\bar w)\\in \\Omega \\quad \\text{and} \\quad \\langle h(\\bar w), v-F(\\bar w) \\rangle + g(v)-g(F(\\bar w)) \\ge 0, \\quad \\forall v\\in \\Omega, \\] where \\(h,F:\\R^d\\to\\R^d\\) are single-valued operators, \\(g:\\Omega\\to\\R\\cup\\{+\\infty\\}\\) is a proper function, and \\(\\Omega\\) is a closed convex set.\n  Two novel continuous-time dynamical systems are proposed to study the finite-time and predefined-time stability of solutions to GIMVIPs in finite-dimensional Hilbert spaces. Under suitable assumptions on the involved operators and model parameters, Lyapunov-based techniques are employed to establish finite-time and predefined-time convergence of the generated trajectories.\n  Although both dynamical systems exhibit accelerated convergence, the settling time of the finite-time stable system depends on the initial condition, whereas the predefined-time stable system admits a uniform upper bound on the convergence time that is independent of the initial state and can be explicitly prescribed through user-selected parameters. Moreover, by applying a forward Euler discretization to the continuous-time dynamics, a proximal point-type iterative algorithm is derived, and its fixed-time convergence property is rigorously analyzed. Numerical experiments are provided to illustrate the effectiveness and advantages of the proposed methods.",
