The College of Science in the Department of Mathematics discussed a seminar entitled Neutrosophic RHO –Ideal with Complete Neutrosophic RHO–Ideal in  RHO–Algebras for postgraduate student Arkan A. Atshan. this seminar aims to introduce and investigated several types of ρ- algebra ideals, which we called neutrosophic ρ- subalgebra, complete neutrosophic ρ- subalgebra, and other types.
