Abstract
Let (A,w) be a finite dimensional n-th order Bernstein algebra over an infinite field K (charK ≠ 2). If e ∈ A is a nontrivial idempotent then A = K e ⊕ U e ⊕ V e where \({U_e} = \left\{ {x \in Kerw/ex = \frac{1}{2}x} \right\}\) and V e = {x ∈ Kerw/R n e x = 0}. In this paper we show the following results:(1) The dimension of U e does not depend on idempotent e,(2) if K = ℝ and dimU e = r then there is an r-parametric family of idempotents of the A, (3) if K = ℝ then dim R V e ≥ n.
