The rest of the answers seem fine.
The Wronskian is a determinant that can be used to determine if a set of solutions is linearly independent, which is a necessary condition for uniqueness of solutions in a system of differential equations. If the Wronskian is non-zero at a given point, then the solutions are linearly independent and the system has a unique solution at that point.
If the Wronskian is non-zero for all points in the domain, then the solutions are linearly independent and the system has a unique solution for all points in the domain. This means that the existence of solutions in a system of differential equations is directly related to the non-zero value of the Wronskian.
No, the Wronskian is primarily used for linear systems of differential equations. For non-linear systems, other methods such as the method of characteristics or the Cauchy-Kovalevskaya theorem may be used to determine existence and uniqueness of solutions.
Boundary conditions play a crucial role in the use of the Wronskian to determine existence and uniqueness. In order for the Wronskian to be a valid determinant, the solutions must satisfy the specified boundary conditions. If the boundary conditions are not satisfied, then the Wronskian may not accurately reflect the uniqueness of solutions.
Yes, there are several limitations to using the Wronskian. It can only be used for linear systems of differential equations, and it is not always a reliable indicator of uniqueness. In some cases, the Wronskian may be non-zero but the solutions may not be unique. Additionally, the Wronskian may not be a valid determinant if the solutions are not smooth or if the boundary conditions are not satisfied.
