Abstract

Let UT4(F)UT_4(F) be 4×44\times 4 upper triangular matrix algebra over a field FF of characteristic zero and let A\mathcal{A} be the subalgebra of UT4(F)UT_4(F) linearly generated by {eij:1ij4}e23\{\mathbf{e}_{ij}:1 \leq i\leq j \leq 4 \} \setminus \mathbf{e}_{23} where {eij:1ij4}\{\mathbf{e}_{ij} : 1 \leq i\leq j \leq 4\} is the standard basis of UT4(F)UT_4(F). We describe the set of all *-polynomial identities for A\mathcal{A} with the involution defined by the reflection of second diagonal.
