randlösungen
Randlösungen refers to the solutions at the boundaries of a domain in mathematical problems, particularly in the field of differential equations. These are not just any solutions, but those that specifically satisfy the conditions imposed on the edges or surfaces of the region where the problem is being solved. For instance, in a one-dimensional problem defined on an interval [a, b], randlösungen would be solutions that meet certain requirements at points a and b. These requirements can take various forms, such as specifying the value of the solution itself (Dirichlet boundary conditions), the value of its derivative (Neumann boundary conditions), or a combination of both (Robin boundary conditions).
The concept of randlösungen is fundamental in the study of partial differential equations (PDEs) and their
