The branching points of the spectrum of an algebraic extension of a uniform algebra $A$ are algebraically described, and the so-called $A$-index of branching of such points is introduced and studied. The description of the character of branching in terms of local point derivations on the algebraic extension is obtained.
Keywords: Banach algebra, algebraic extension, $A$-index of branching, point derivation.
