    I learned them in high school, and they are still used in Poland, but at
    the University all used A,E. What is interesting I haven't found those
    V-like symobls in Comprehensive LaTeX Symbols List (that's strange,
    isn't it?).

    Probably they are used only in Europe.

    No, they cannot be glyph variants. There is very big different in usage.
    Those A,E shapes are _linear_ in form, the V-like symbols ARE NOT. The
    condition after A,E symbol is written AFTER the symbols and in the V
    standard the condition is usually written _UNDER_ the symbol.
