Chiral Transition and Baryon-number Susceptibility
  We discuss the baryon-number susceptibility $\chi_B$ and related topics which include the density fluctuations around the critical point of the chiral transition at finite temperature $T$ and baryon density $\rho_B$. Phenomenological implications of the density fluctuations near the first-order chiral transition at finite density are also discussed.
