摘要：

In the framework of the extended Hubbard model (copper-oxygen and oxygen-oxygen hopping) the energy and effective mass of a mobile hole is expressed in terms of hopping parameters and the correlators between spins of the background <S(n)S(n+1)>. Due to interaction of the mobile hole with localized holes, its effective mass increases about four times.
