In this talk we will examine a modification of the Grothendieck-Katz $p$-curvature conjecture considered by Yunqing Tang in her paper "Algebraic Solutions of Differential Equations over $\Bbb P^1\setminus \{0,1,\infty \}$," in which a condition has been placed on a connection $(M,\nabla )$ at all primes rather than at almost all primes. We will recall the classical $p$-curvature conjecture, introduce its strengthened variant, and discuss the proof of Tang's results.
