  Exactly solvable $N$-dimensional model of the quantum isotropic singular
oscillator in the relativistic configurational $\vec r_N$-space is proposed. It
is shown that through the simple substitutions the finite-difference equation
for the $N$-dimensional singular oscillator can be reduced to the similar
finite-difference equation for the relativistic isotropic three-dimensional
singular oscillator. We have found the radial wavefunctions and energy spectrum
of the problem and constructed a dynamical symmetry algebra.
