Involution codimensions of Grassmann algebra (Q1851540)

The author obtains exact values of *-codimensions \(c_n(\Lambda,*)\) of identity ideals of infinite-dimensional Grassmann algebra \(\Lambda\) with generating set \(\{e_i\}\) for the involutions \(*=\varphi_{\text{id}}\), \(\varphi_{\text{id}}(e_i) = e_i\) and \(*=\varphi_{12}\), \(\varphi_{12}(e_{2k-1}) = e_{2k}\), \(\varphi_{12}(e_{2k}) = e_{2k-1}\), \(k=1,2,\dots\).
