A Square as a mathematical symbol/operator

  1. Mar 18, 2008 #1
    I am pretty well familiar with most operators, but a square I am not so sure about. I've been trying to find a link to a complete list of currently used mathematical symbols online but I haven't found one. Could somebody please help me out. Thx...............

    The d'Alembertian is usually denoted by a square in physics texts.

    Steinhaus' polygon notation is usually represented as a square with an infix argument.

    I do believe it would be the d'Alembert Operator as it is an equation relating to time dependant oscillations in three dimensional space................

    Thanx a bunch
