This book provides the foundations for a rigorous theory of functional
analysis with bicomplex scalars. It begins with a detailed study of
bicomplex and hyperbolic numbers and then defines the notion of
bicomplex modules. After introducing a number of norms and inner
products on such modules (some of which appear in this volume for the
first time), the authors develop the theory of linear functionals and
linear operators on bicomplex modules. All of this may serve for many
different developments, just like the usual functional analysis with
complex scalars and in this book it serves as the foundational material
for the construction and study of a bicomplex version of the well known
Schur analysis.
