DESCRIPTION:Title: <a href="https://researchseminars.org/talk/qc_seminar/6
 /">Accumulation of resonances and eigenvalues for operators with distant p
 erturbations</a>\nby Denis Borisov (Bashkir State Pedagogical University\,
  Ufa) as part of Quantum Circle\n\n\nAbstract\nWe consider a model one-dim
 ensional problem with distant perturbations\, for which we study a phenome
 non of emerging of infinitely many eigenvalues and resonances near the bot
 tom of the essential spectrum. We show that they accumulate to a certain s
 egment of the essential spectrum. Then we discuss possible generalization 
 of this result to multi-dimensional models and various situations of reson
 ances and eigenvalues distributions.\n
