     Hutch++ improves upon Girard-Hutchinson estimator by including the trace of the residuals. Namely,
-    Hutch++ estimates $\\text{trace}(\mathbf{A})$ as
-    $\\text{trace}(\hat{\mathbf{A}}) - \\text{trace}(\mathbf{A} - \hat{\mathbf{A}})$.
+    Hutch++ estimates $\text{trace}(\mathbf{A})$ as
+    $\text{trace}(\hat{\mathbf{A}}) - \text{trace}(\mathbf{A} - \hat{\mathbf{A}})$.
 
     As with the Girard-Hutchinson estimator, it requires
     $\mathbb{E}[\omega] = 0$ and $\mathbb{E}[\omega \omega^T] = \mathbf{I}$.
