Let  $f:M\rightarrow M$  be a
$f:M\rightarrow M$  be a  $C^{1}$  self-map of a smooth Riemannian manifold
$C^{1}$  self-map of a smooth Riemannian manifold  $M$  and
$M$  and  $\unicode[STIX]{x1D707}$  be an

$f$ -invariant ergodic Borel probability measure with a compact support  $\unicode[STIX]{x1D6EC}$ . We prove that if
$\unicode[STIX]{x1D6EC}$ . We prove that if  $f$  is Hölder mild on the intersection of the singularity set and
$f$  is Hölder mild on the intersection of the singularity set and  $\unicode[STIX]{x1D6EC}$ , then the pointwise dimension of

$\unicode[STIX]{x1D707}$  can be controlled by the Lyapunov exponents of  $\unicode[STIX]{x1D707}$  with respect to
$\unicode[STIX]{x1D707}$  with respect to  $f$  and the entropy of
$f$  and the entropy of  $f$ . Moreover, we establish the distinction of the Hausdorff dimension of the critical points sets of maps between the
$f$ . Moreover, we establish the distinction of the Hausdorff dimension of the critical points sets of maps between the  $C^{1,\unicode[STIX]{x1D6FC}}$  continuity and Hölder mildness conditions. Consequently, this shows that the Hölder mildness condition is much weaker than the
$C^{1,\unicode[STIX]{x1D6FC}}$  continuity and Hölder mildness conditions. Consequently, this shows that the Hölder mildness condition is much weaker than the  $C^{1,\unicode[STIX]{x1D6FC}}$  continuity condition. As applications of our result, if we study the recurrence rate of
$C^{1,\unicode[STIX]{x1D6FC}}$  continuity condition. As applications of our result, if we study the recurrence rate of  $f$  instead of the pointwise dimension of
$f$  instead of the pointwise dimension of  $\unicode[STIX]{x1D707}$ , then we deduce that the analogous relation exists between recurrence rate, entropy and Lyapunov exponents.
