A representation and comparison of three cubic macro-elements

Ema Češek, Jan Grošelj, Andrej Kolar-Požun +4

The paper is concerned with three types of cubic splines over a triangulation that are characterized by three degrees of freedom associated with each vertex of the triangulation. T…

Logarithmic growth of operator entanglement in a clean non-integrable circuit

Mao Tian Tan, Tomaž Prosen

We study a so-called semi-ergodic brickwork dual-unitary circuits where, in the infinite volume limit, the two-point correlation functions of single-site operators exhibit ergodic…

Neumann problem with a discontinuous nonlinearity

Debajyoti Choudhuri, Dušan D. Repovš, Kamel Saoudi

This study is devoted to proving the existence of weak solutions for a nonlinear elliptic problem with Neumann-type boundary data. The problem is driven by a discontinuous power no…

Random discrete copulas

Damjana Kokol Bukovšek, Blaž Mojškerc, Nik Stopar

We introduce the notion of a bivariate random discrete copula on an equidistant mesh and explore its stochastic properties. A random discrete copula is a discrete random field, hen…

Studies of the Roper Resonance by the Ljubljana Group

Simon Sirca

Ever since its discovery in 1964 the nature of the N*(1440) nucleon resonance has been a perpetual and one of the outstanding puzzles in hadronic physics. The Ljubljana group joine…
