[Todos] Jenia Tevelev en el coloquio del DM el miércoles 20 de mayo

[Coloquio DM]

Estimados/as,

tengo el placer de anunciar que el próximo coloquio del Departamento de
Matemática (FCEN-UBA) será el miércoles 20 de mayo las 17hs, en modalidad
virtual.

Hablará Jenia Tevelev, de la University of Massachusetts at Amherst (de
sabático en 2019-2020 en la PUC, Santiago de Chile).

The forest behind the hypertrees: scattering amplitudes from stable curves

Hypertree divisors on the Grothedieck--Knudsen moduli space of stable
rational curves with n marked points were introduced by Castravet and
Tevelev to study its birational geometry. These divisors have determinantal
equations, which, quite mysteriously, appear in the work of Arkani-Hamed,
Bourjaily, Cachazo, Postnikov and Trnka
as numerators of scattering amplitudes (also known as S-matrices) for n
massless particles in 4-dimensional supersymmetric Yang--Mills theory.
Rather than being a  coincidence, this turns out to be just the tip of the
iceberg of amusing relations between geometry of Riemann surfaces and high
energy physics. In this talk, directed towards general audience, we will go
on a tour of old and new results in algebraic geometry inspired and
reinterpreted by scattering amplitudes.

Volveremos a contactarlos para brindarles instrucciones para acceder.

Saludos cordiales,
Inés Armendáriz
