Abstract: **Main Theorem.** *Let* *be a prime ring with involution* . *Suppose that* *is a* -*differential identity for* , *where* *are distinct regular words of derivations in a basis* *with respect to a linear order* *on* . *Then* *is a* -*generalized identity for* , *where* *are distinct indeterminates*.

Along with the Main Theorem above, we also prove the following:

**Proposition 1.** *Suppose that* *is of the second kind and that* *is infinite. Then* *is special*.

**Proposition 2.** *Suppose that* . *Then* , *the two-sided quotient ring of* , *is equal to* .

**Proposition 3** (Density theorem). *Suppose that* *and* *are dual spaces with respect to the nondegenerate bilinear form* . *Let* *and* *be such that* *is* -*independent in* *and* *is* -*independent in* . *Then there exists* *such that* *and* *if and only if* *for* *and* .

**Proposition 4.** *Suppose that* *is a prime ring with involution* *and that* *is a* -*generalized polynomial. If* *vanishes on a nonzero ideal of* , *than* *vanishes on* , *the two-sided quotient ring of* .
