Linear Ordinary Differential Equations with Boundary Conditions on Arbitrary Point Sets
Linear Ordinary Differential Equations with Boundary Conditions on Arbitrary Point Sets
Boundary-value problems for differential operators A of order 2m which are the Euler derivatives of quadratic functionals are considered.The boundary conditions require the solution F to coincide with a given function fe 3fL(R) at the points of an arbitrary closed set B, to satisfy at the isolated points of B …
