In summary, a boundary value problem is a mathematical problem that involves finding a solution to a differential equation with specified conditions at the boundaries of the domain. It becomes non-linear when the differential equation contains non-linear terms, making it more complex to solve. Common techniques for solving non-linear BVPs include numerical and analytical methods, but these can be challenging and time-consuming. However, these problems have real-world applications in various fields, such as science, engineering, and economics.

A boundary value problem is a type of mathematical problem that involves finding a solution to a differential equation with specified conditions at the boundaries of the domain. These conditions can include values of the solution, derivatives of the solution, or a combination of both.

A boundary value problem is considered non-linear if the differential equation involved contains non-linear terms, such as powers, products, or trigonometric functions, which cannot be expressed as a linear combination of the dependent variable and its derivatives. This makes the problem more complex and often requires different methods for solving.

There is no one method for solving all types of non-linear boundary value problems. However, some common techniques include numerical methods, such as the shooting method or finite difference method, and analytical methods, such as the power series method or perturbation method. The specific approach will depend on the specific problem and the tools and techniques available.

Non-linear boundary value problems can be significantly more difficult to solve compared to linear problems. This is because non-linear equations often have multiple solutions or no solutions at all. Additionally, the methods used for solving non-linear problems can be time-consuming and require extensive computational resources.

Non-linear boundary value problems are used to model and solve various phenomena in the natural and physical sciences, engineering, and economics. For example, they can be used to study the behavior of complex systems, such as weather patterns, population dynamics, or chemical reactions. Solving these problems can provide valuable insights and help make predictions for real-world applications.
