    This paper studies a bidirectional two-lane asymmetric exclusion process, in which particles move in opposite direction on the two lanes. Interaction between the two lanes is implemented as follows: particle hops with rate p when there is a particle at the same site in the other lane, otherwise...

    We consider a parabolic semilinear problem with rapidly oscillating coefficients in a domain Oe that is e-periodically perforated by small holes of size $\mathcal {O}$(e). The holes are divided into two e-periodical sets depending on the boundary interaction at their surfaces, and two different...

    In this work we study the problem - div(|∇u|p-2∇u) = λf(u) in the unit ball of RN, with u = 0 on the boundary, where p > 2, and λ is a real parameter. We assume that the nonlinearity f has a zero u0 > 0 of order k ≥ p - 1. Our main contribution is showing that there...

    The computation of consistent initial values is one of the basic problems solving initial or boundary value problems of DAEs. The difficulties to compute consistent initial values start before a numerical computation. For a given DAE it is not obvious how to formulate the initial conditions...
