On ideals of the group algebra of a free group of degree of freedom two over the field of complex numbers
In this paper, we prove the existence of an elementα of the group algebra $A=ℂF$ of a free group $F$ with two generatorsx andy over the field of complex numbers $C$ such that, for any complex $a$ and $b$ for which $¦a¦=¦b¦=1$, we have $A ∩ ϑ_{a,b} (α)A=0$, where $ϑ_{a,b}$ ($α$ is an automorphism of...

Thus, we give a negative answer to question 12.46 of P. A. Linnel from “Kourovka Notebook.” |
