Eigenfunction Expansions and Scattering Theory for Dirac Operators
Eigenfunction Expansions and Scattering Theory for Dirac Operators
in R 3, where a,- and /? are the so-called Dirac matrices and Q(x) is a Hermitian symmetric potential decaying at infinity with like Ixl1'1, /i>0. More detailed assumptions will be mentioned in §2. Eigenfunction expansions and scattering problems for Dirac operators have been investigated by many authors. Titchmarsh [14] …
