DESCRIPTION:Title: A cornucopia of surprises: the Riemann Hypothesis at 162\nby Jorge
Buescu (FCUL\, Lisbon) as part of Colóquio de Matemática - FCUL\n\nLect
ure held in Sala 6.2.33.\n\nAbstract\nThe Riemann Hypothesis (RH) is argua
bly the most important unsolved problems in Mathematics\, being one of the
outstanding Millenium Problems. In this talk we provide a bird’s eye vi
ew of RH as Riemann conceived it\, showing its connection to the exact for
mula for distribution of primes\; we describe some classical results relat
ed to RH derived during its first century of life\; and we sketch several
modern approaches which lead to unexpected connections to other branches o
f Mathematics\, including the ghostly appearance of the critical strip in
the author’s apparently unconnected research.\n\npassword: coloquioDM\n

DESCRIPTION:Title: Eulerian polynomials via the Weyl algebra action\nby José Agapito
Ruiz (Fac. de Ciências\, Univ. de Lisboa) as part of Colóquio de Matem
ática - FCUL\n\nLecture held in Sala 6.2.33.\n\nAbstract\nUsing the frame
work of partitions and rook placements\, we study\, in particular\, the ac
tion of the Weyl algebra on the geometric series\, obtaining a generalizat
ion of the Worpitzky identity and new recursive formulas for a family of p
olynomials that include the classical Eulerian polynomials.\n\nThis is joi
nt work with Pasquale Petrullo\, Domenico Senato\, and Maria Manuel Torres
