Special number sequences—such as Fibonacci, Lucas, Horadam and Jacobsthal families—exhibit rich algebraic structures that underpin a broad spectrum of mathematical theory and application. At their ...

Hirzebruch's problem at the interface of topology and algebraic geometry has occupied mathematicians for more than 50 years. A professor of mathematics at the Ludwig-Maximilians-Universitaet in Munich ...

In 1886 the mathematician Leopold Kronecker famously said, “God Himself made the whole numbers — everything else is the work of men.” Indeed, mathematicians have introduced new sets of numbers besides ...
