With the help of the Weierstrass elliptic functions, we study the problem of describing the Nuttall decomposition of a three-sheeted compact Riemann surface of genus $1$ related to an Abelian integral on the surface. This decomposition plays an important role in investigation of Hermite–Padé diagonal approximations.
Keywords: Hermite–Padé diagonal approximation, Riemann surface, elliptic function, Abelian integral, quadratic differential, complex torus.
