SUMMARY:The present and future of flavor in high-energy cosmic neutrin
 os\, Network in Neutrinos\, Nuclear Astrophysics\, and Symmetries (N3A
 S) Seminar\, Mauricio Bustamante \, NBIA\, Denmark
DESCRIPTION:The flavor composition of high-energy cosmic neutrinos\, i
 .e.\, the proportion of neutrinos of different flavor in their flux---
 electron\, muon\, and tau---is a versatile observable to test astrophy
 sics and particle physics.  For astrophysics\, it allows us to identif
 y the neutrino production process and so narrow down the identity of t
 heir sources. For fundamental physics\, it allows us to probe physics 
 beyond the Standard Model at hitherto untested energies.  Yet\, so far
 \, the experimental difficulties involved in measuring flavor composit
 ion in IceCube have hampered its physics reach.  Fortunately\, this ma
 y be for not much longer\, thanks to upcoming\, larger neutrino telesc
 opes.  I will show state-of-the-art forecasts for the measurement of t
 he flavor composition of TeV-PeV cosmic neutrinos in the next two deca
 des using the combined detection by multiple neutrino telescopes.  Tog
 ether\, they could enable measurements of the energy dependence of the
  flavor composition---revealing changes in the neutrino production pro
 cess---and of its directional dependence---revealing flavor asymmetrie
 s in the high-energy neutrino sky.  I will conclude by proposing novel
  techniques to extend flavor-composition measurements to ultra-high en
 ergies\, beyond 100 PeV\, using large-scale neutrino radio-detection i
 n IceCube-Gen2 and GRAND.<br>
