RT Journal Article T1 Polynomial Inequalities on the π/4-Circle Sector A1 Araujo, G. A1 Jiménez Rodríguez, P. A1 Muñoz-Fernández, Gustavo A. A1 Seoane-Sepúlveda, Juan B. AB A number of sharp inequalities are proved for the space P (2D (π/4)) of 2-homogeneous polynomials on ℝ2 endowed with the supremum norm on the sector D (π/4) := {eiθ : θ ∈ [0, π/4]}. Among the main results we can find sharp Bernstein and Markov inequalities and the calculation of the polarization constant and the unconditional constant of the canonical basis of the space P (2D (π/4)).
