The Fredholm alternative states that, for any non-zero fixed complex number, either the first equation has a non-trivial solution, or the second equation has a solution for all . A sufficient condition for this theorem to hold is for to be square integrable on the rectangle (where a and/or b may be minus or plus infinity).

Then, if n 6= 0 for all n, u= X n f n n ˚ FREDHOLM ALTERNATIVE 3 its null space is one dimensional, spanned by the derivative @ u 0 of the wave train = 0 simple also implies that @ u 0 is not in the range of L 0. If it were, then 9u 1 s.t. L 0u 1 = u 0, implying that = 0 is part of a Jordan block of dimension at least 2, which violates the simple hypothesis. The Fredholm Alternative Theorem can be easily understood if you consider solutions to the matrix equation, for a matrix and vectors and. Everything that applies to matrices can then be generalized to infinite dimensional linear operators that occur in differential or integral equations. In the finite-dimensional case, the Fredholm alternative is an immediate consequence of the rank-nullity theorem, and the finite rank case can be easily deduced from the finite dimensional case by some routine algebraic manipulation.

It may be expressed in several ways, as a theorem of linear algebra, a theorem of integral equations, or as a theorem on Fredholm operators. In der Mathematik ist die nach Ivar Fredholm benannte Fredholmsche Alternative ein Resultat der Fredholmtheorie. Sie kann auf verschiedene Arten ausgedrückt werden: als Theorem der linearen Algebra, als ein Theorem über Integralgleichungen oder als ein Theorem über Fredholm-Operatoren. Insbesondere besagt es, dass eine komplexe Zahl ungleich 0 im Spektrum eines kompakten Operators ein Eigenwert ist. of course, you could just multiply the equation by $\cos x$ and integrate from $-\pi$ to $\pi$ and use integration by parts to obtain $0 = 1.$ this is what fredholm alternative really is.
