Can deep learning techniques predict sudden state transitions in nonlinear dynamical systems?
Nonlinear dynamical systems are systems that can undergo sudden shifts not due to changes in their state or stability, but in response to the rate at which external conditions or parameters change. These sudden shifts, known ...
How much faster is a knight than a king? A mathematical study reveals the exact ratio
We know a knight can move across the chessboard faster than the king, but exactly how much faster? Christian Táfula Santos, a doctoral student in UdeM's Department of Mathematics, has done the math and his proof has been ...
