Given a positive integer n, we let sfp(n) denote the squarefree part of n. We determine all positive integers n for which max{sfp(n),sfp(n+1),sfp(n+2)}<=150 by relating the problem to finding …

We consider matrix-vector equations of the form Ax = f(x) that are motivated by nonlinear oscillating systems such as the Tacoma Narrows Bridge. We identify a particular set, called the Fučı´k …
