Inequalities

<p>Inequalities appear in various fields of natural science and engineering. Classical inequalities are still being improved and/or generalized by many researchers. That is inequalities have been actively studied by mathematicians. In this book we selected the papers that were published as the Special Issue ‘’Inequalities’’ in the journal <em>Mathematics</em> (MDPI publisher). They were ordered by similar topics for readers’ convenience and to give new and interesting results in mathematical inequalities such as the improvements in famous inequalities the results of Frame theory the coefficient inequalities of functions and the kind of convex functions used for Hermite–Hadamard inequalities. The editor believes that the contents of this book will be useful to study the latest results for researchers of this field.</p>
