There are many things named after him:

• Darboux integral
• Darboux function
• Darboux's theorem (see Intermediate value theorem for now)
• Christoffel-Darboux identity [1]
• Christoffel-Darboux formula [2]
• Darboux's formula [3]
• Darboux vector [4]
• Euler-Darboux equation [5]
• Euler-Poisson-Darboux equation [6]
• Darboux cubic [7]
• Darboux [8] or Goursat problem [9]
