Value at risk and the distortion operator
… fit the actual market conditions. If finding a mathematical tool to bridge to theoretical model with reality were possible, we could expect a better or less expensive estimation of the VaR. Calculation of the actual VaR for an asset can be started by first finding the risk adjusted return under …

Time-evolution of SU(2) lattice gauge theory on a quantum computer
Lattice Gauge Theory is a mathematical tool used to study the forces of nature, like Quantum Electrodynamics and Quantum Chromodynamics. Quantum computers offer an alternative to classical computers in studying these forces. In my thesis, a gate-based quantum computer was used to perform …

Optimal dynamic pricing for clearance sales on the spot market
… in this thesis provide the company with a mathematical tool which can be used to optimally and dynamically set prices to maximize the profits in the clearance sales. We assume that buyers are myopic, demand multiple units of products and have independent demand. We also assume that the …

Control of Periodic Systems Governed by Partial Differential Equations Using Averaging
As a perturbation method, averaging is a mathematical tool for dynamic analysis of time-periodic and space-periodic dynamical systems, including those governed by partial differential equations. The control design procedure presented in this work uses averaging techniques, the well-developed linear …

TENSOR NETWORKS FOR OPEN QUANTUM SYSTEMS
… modest sizes. Tensor networks provide a powerful mathematical tool to address this issue: by efficiently representing only a low-entanglement subspace of the full space of states, they mitigate the exponential scaling and enable faster computations. Their intuitive diagrammatic language makes them …
