GEOMETRY OF UNITARIES IN A FINITE ALGEBRA: VARIATION FORMULAS AND CONVEXITY
Given a C*-algebra [Formula: see text] with trace τ, we compute the first and second variation formulas for the p-energy functional F p of the unitary group [Formula: see text] of [Formula: see text], for p = 2n an even integer, namely: [Formula: see text] where [Formula: see text] is …
