by Otto Schreier in 1927, and later in the theory of Lie algebras by
Pyotr Shirshov in 1948.
It is a powerful construction which allows us to combine multiple
algebraic structures into a single, unified object, while preserving
important properties of each individual structure. </div><div dir="auto">In this talk, we will explore free products with amalgamation in the
context of groups, Lie algebras, and associative algebras, and see how
they behave moving from one context to the other.
We will eventually show under which conditions the functor associating
to a group with the graded Lie algebra induced by the lower central
filtration preserves such construction.</div><div dir="auto"><br></div><div dir="auto"><font color="#000000"><u>Keywords:</u></font> Groups, Lie algebras, free product with amalgamation</div><div dir="auto"><br></div><div dir="auto"><div dir="auto"><u><b>Information to attend in room 3014</b></u></div><div dir="auto">The seminar will take place in room 3014, at the building U5-Ratio, Università degli Studi di Milano Bicocca.</div><div dir="auto"><br></div><div dir="auto"></div><div dir="auto"><u><b>Information to attend online<br></b></u></div><div dir="auto"><a href="https://unimib.webex.com/unimib/j.php?MTID=m101728a0c0258813b6aa97783fb11fad" target="_blank">https://unimib.webex.com/unimib/j.php?MTID=m101728a0c0258813b6aa97783fb11fad</a> (password: insalate, 46725283 from phones)</div><div dir="auto"><br></div><div dir="auto"><div dir="auto">You can find the poster of the event in the attachment. </div><div dir="auto">We are looking forward to seeing you! </div><div dir="auto"><br></div><div dir="auto"></div><div dir="auto">For further information, please visit our website: <a href="https://sites.google.com/view/insalate-di-matematica" rel="noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer" target="_blank">https://sites.google.com/view/insalate-di-matematica</a> or contact us at <a href="mailto:insalate.matematica@unimib.it" rel="noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer" target="_blank">insalate.matematica@unimib.it</a>.
