The book is mainly about hybrid systems with continuous/discrete-time
dynamics. The major part of the book consists of the theory of equations
with piece-wise constant argument of generalized type. The systems as
well as technique of investigation were introduced by the author very
recently. They both generalized known theory about differential
equations with piece-wise constant argument, introduced by K. Cook and
J. Wiener in the 1980s. Moreover, differential equations with fixed and
variable moments of impulses are used to model real world problems. We
consider models of neural networks, blood pressure distribution and a
generalized model of the cardiac pacemaker. All the results of the
manuscript have not been published in any book, yet. They are very
recent and united with the presence of the continuous/discrete dynamics
of time. It is of big interest for specialists in biology, medicine,
engineering sciences, electronics. Theoretical aspects of the book meet
very strong expectations of mathematicians who investigate differential
equations with discontinuities of any type.
