In particular, we will consider trees as languages, provide an idea of automata and use them for our geometric purpose.</div><div dir="auto"><br></div><div dir="auto"><i><u>Keywords</u></i>: trees - hyperbolic graphs - automata</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><b>** We inform you that the talk will be recorded and uploaded on our website.
