 abstract = {We study here different regions in phase diagrams of the spin-1/2,
spin-1 and spin-3/2 one-dimensional antiferromagnetic Heisenberg systems
with frustration (next-nearest-neighbor interaction J(2)) and
dimerization (delta). In particular, we analyze the behaviors of the
bipartite entanglement entropy and fidelity at the gapless to gapped
phase transitions and across the lines separating different phases in
the J(2)-delta plane. All the calculations in this work are based on
numerical exact diagonalizations of finite systems.},
