   To define the #{\varphi_x}, we consider the complex #{K_x} whose underlying #{A}-modules are the #{\wedge A^p}, and whose differential is the interior product #{i_x} by #{x}, considered as a linear form on #{A^p} with components #{x_1,\ldots,x_p}.
   The differential is of degree #{-1}, the degrees of the complex are positive, and the cohomology of this complex in dimension #{0} is #{A/(x_1A+\ldots+x_pA)}.
   Since the #{x_i} are in #{\mathfrak{J}}, we obtain an augmentation #{K_{x,0}\to A/\mathfrak{J}}.
-  Thus #{K_x} is a _free_ augmented complex, with augmentation module #{A/\mathfrak{J}}.
+  Thus #{K_x} is a \em{free} augmented complex, with augmentation module #{A/\mathfrak{J}}.
   We thus obtain known homomorphisms
