Cross-domain applications within the quantum framework: From the theory of infinite-dimensional operators to quantum cognitive science and quantum game theory
易先 周
The theory of infinite-dimensional operators provides a powerful mathematical foundation for modern physics and cognitive science. This paper starts by exploring the differences between linear operators in finite-dimensional and infinite-dimensional spaces, and then discusses their applications in quantum field theory, quantum probabilistic decision theory, quantum cognitive science, and quantum game theory. Through concepts such as Hilbert spaces, projection operators, quantum interference, and entanglement, this paper demonstrates how the quantum framework can transcend classical models and more accurately describe uncertainty, context dependence, and policy interactions in complex systems. Finally, the latest real-world developments in this research are discussed.
