Graph algebras form a broad class of operator and algebraic structures arising from directed graphs, bridging the worlds of ring theory, operator algebras and dynamical systems. At their core, these ...

Plotting a graph takes time. Often mathematicians just want to know the key features. These are: shape, location and some key points (such as where the graph crosses the axes or turning points). So ...
