Zero Polynomial
The constant polynomial 
whose coefficients
are all equal to 0. The corresponding polynomial function is the constant
function with value 0, also called the zero map.
The zero polynomial is the additive identity
of the additive group of polynomials.
The degree of the zero polynomial is undefined, but many authors conventionally set it equal to 
or 
. In the Wolfram Language, Exponent[0,
x] returns -Infinity.
