The suspicion, harbored by many physicists and mathematicians over the decades but rarely actively pursued, is that the peculiar panoply of forces and particles that comprise reality spring logically ...

Tessellations aren’t just eye-catching patterns—they can be used to crack complex mathematical problems. By repeatedly reflecting shapes to tile a surface, researchers uncovered a method that links ...

For q > 0 let A denote the unital ∗-algebra with generator x and defining relation xx* = qx*x. Based on this algebra we study q-normal operators and the complex q-moment problem. Among other things, ...
