On the Density of Real Quadratic Fields with λ₂=μ₂=ν₂=0

抄録

According to the previous works by Nakagawa-Horie and the first author, the density of real quadratic fields with λ₃=μ₃=ν₃=0 is greater than or equal to \\frac{17}{24}. In this note, however, we will report the density of real quadratic fields with λ₂=μ₂=ν₂=0 to be zero.
