\begin{definition}[Definition:Boubaker Polynomials]
The Boubaker polynomials are the components of the following sequence of polynomials:
{{begin-eqn}}
{{eqn | l = \map {B_0} x
      | r = 1     
}}
{{eqn | l = \map {B_1} x
      | r = x     
}}
{{eqn | l = \map {B_2} x
      | r = x^2 + 2     
}}
{{eqn | l = \map {B_3} x
      | r = x^3 + x     
}}
{{eqn | l = \map {B_4} x
      | r = x^4 - 2     
}}
{{eqn | l = \map {B_5} x
      | r = x^5 - x^3 - 3 x     
}}
{{eqn | l = \map {B_6} x
      | r = x^6 - 2 x^4 - 3 x^2 + 2     
}}
{{eqn | l = \map {B_7} x
      | r = x^7 - 3 x^5 - 2 x^3 + 5 x     
}}
{{eqn | l = \map {B_8} x
      | r = x^8 - 4 x^6 + 8 x^2 - 2     
}}
{{eqn | l = \map {B_9} x
      | r = x^9 - 5 x^7 + 3 x^5 + 10 x^3 - 7 x     
}}
{{eqn | o = \vdots}}
