CORRECTION

In my note published in Dokl. Akad. Nauk, vol. 112, no. 5, 1957 (B. G. Korenev, “A stamp resting on an elastic half-space whose modulus of elasticity is a power function of depth”), the following corrections should be made:

1) The notation (w_0^(\rho)) should have the form (w_0^(\rho)=R w_0(r)).

2) Formula (18) should have the form:

[
p(\rho)=
\frac{2\pi g_0 2^{\frac{1-n}{2}}}{\Gamma!\left(\frac{n+1}{2}\right)}
\int_{0}^{\infty}
\beta^{\frac{1-n}{2}} J_{n+\frac12}(\beta)J_0(\beta\rho)\,d\beta,
\tag{18}
]

whence

[
p(\rho)=
\frac{4\pi g_0}{2^n\Gamma^2!\left(\frac{n+1}{2}\right)}
F_1!\left(1,\frac{1-n}{2};1;\rho^2\right)
=
\frac{4\pi g_0}{2^n\Gamma^2!\left(\frac{n+1}{2}\right)}
\frac{1}{(1-\rho^2)^{\frac{1-n}{2}}}.
]
