<i>Title:</i> Towers and elementary embeddings in toral relatively hyperbolic groups<strong></strong> <div>
<p>
<em>Abstract:
</em>In a remarkable series of papers, Zlil Sela classified the first-order
theories of free groups and torsion-free hyperbolic groups using
geometric structures he called towers. It was later proved by Chloé
Perin that if H is an elementarily embedded subgroup (or elementary
submodel) of a torsion-free hyperbolic group G, then G is a tower over
H. We prove a generalization of Perin's result to toral relatively
hyperbolic groups using JSJ and shortening technique<em>s
