• Superconformal indices at large N and the entropy of AdS5 × SE5 black holes 

  Benini, Francesco; Colombo, Edoardo; Soltani, Saman; Zaffaroni, Alberto; Zhang, Ziruo (SISSA, 2020-05)

  The large N limit of the four-dimensional superconformal index was computed and successfully compared to the entropy of a class of AdS5 black holes only in the particular case of equal angular momenta. Using the Bethe ...
• Forward untangling and applications to the uniqueness problem for the continuity equation 

  Bianchini, Stefano; Bonicatto, Paolo (SISSA, 2020-05)
• On the sticky particle solutions to the multi-dimensional pressureless Euler equations 

  Bianchini, Stefano; Daneri, Sara (SISSA, 2020-05)

  In this paper we consider the multi-dimensional pressureless Euler system and we tackle the problem of existence and uniqueness of sticky particle solutions for general measure-type initial data. Although explicit ...
• Periodic solutions of second order differential equations in Hilbert spaces 

  Fonda, Alessandro; Klun, Giuliano; Sfecci, Andrea (SISSA, 2020-05)

  We prove the existence of periodic solutions of some infinite-dimensional systems by the use of the lower/upper solutions method. Both the well-ordered and non-well-ordered cases are treated, thus generalizing to systems ...
• Non-well-ordered lower and upper solutions for semilinear systems of PDEs 

  Fonda, Alessandro; Klun, Giuliano; Sfecci, Andrea (SISSA, 2020-05)

  We prove existence results for systems of boundary value problems involving elliptic second order differential operators. The as-sumptions involve lower and upper solutions, which may be either well-ordered, or not at all. ...
