This book addresses recent developments in sign patterns for generalized inverses. The fundamental importance of the fields is obvious, since they are related with qualitative analysis of linear systems and combinatorial matrix theory. The book provides both introductory materials and discussions to the areas in sign patterns for Moore–Penrose inverse, Drazin inverse and tensors. It is intended to convey results to the senior students and readers in pure and applied linear algebra, and combinatorial matrix theory.

Preface
Generalized inverse has wide applications in science and engineering. The sign
pattern of generalized inverses has an important theoretical significance and
application value in the problems of qualitative analysis of systems and
Combinatorial Matrix Theory.
P.A. Samuelson, a Nobel Prize winner in economics, attributed the qualitative
analysis of an economics model to the problem of the sign-solvability for a linear
system, which opened the research of the sign pattern of matrices. After that,
R.A. Brualdi, an AMS fellow, and B.L. Shader, a SIAM fellow, systematically
investigated the sign pattern for the inverse of a matrix, which established the basic
theory of the sign pattern of generalized inverses. From 1995 to 2003, B.L. Shader,
Jia-Yu Shao and other scholars studied the sign pattern of the Moose–Penrose
inverse of matrices, and obtained a series of important results.
In 2010, P. van den Driessche, M. Catral and D.D. Olesky provided the group
inverses for the adjacency matrices of a class of broom graphs, and proved the sign
pattern of this kind of matrices is unique. In 2011, we proposed the concept of the
sign group invertible matrix, the strongly sign group invertible matrix and the
matrix with unique sign Drazin inverse, and established many new results on the
associated characterization. Furthermore, we extended the research to the ray
pattern of complex matrices, and characterized the matrices with ray
Moore–Penrose inverse and ray Drazin inverse. Also, we first studied the sign pattern of tensors.
The sign pattern of generalized inverses is not only an extension and a
development of the sign pattern of matrices but also a new front topic. There are many
groundbreaking research problems which need new ideas to be solved. This
monograph introduces the technical methods of characterizing the sign of generalized
inverses and review the status of the newest research on this topic, which can be used
as a reference or textbook for researchers or graduate students in matrix theory,
combinatorics algebra etc.
