" Krein
spaces numerical ranges and their computer generation "
Abstract. Let J be an involutive Hermitian matrix
with signature (t,n-t), that is, with t positive and n-t negative
eigenvalues. The Krein space numerical range of a complex matrix A of
size n is the collection of complex numbers of the form x*JAx/x*Jx,
with x in C^n and x*Jx different from zero. In this talk, properties of
this numerical range are discussed. Matlab programs are developed to
generate Krein spaces numerical ranges in the finite dimensional case.
