Aim of these notes is to provide a self-contained presentation of recents results on hyperbolic systems of conservation laws, based on the vanishing viscosity approach. A system of conservation laws in one space dimension takes the form u t + f (u) x = 0. (1.1) Here u = (u 1 ,. .. , u n) is the vector of conserved quantities while the components of f = (f 1 ,. .. , f n) are called the fluxes. I...

änderung der Kernvolumina wurde schon • an Drüsenzellen, also im Sinne G. B i z z o z e r o s an stabilen Zellen, vermutet und wird hier an labilen (Hautepithel) und perennen (Nervenzellen) Zellen bestätigt. Sie kann damit als allgemeines Gesetz aufgestellt werden. So wird die Methode der Kernmessung ein W e g zur Klärung mancher Funktionsprobleme der Zelle. H r n . P r o f . D r . A . B e n n ...

and Applied Analysis 3 We first list the definition of cone and the compression and expansion fixed point theorem 20, 22 . Definition 2.1. Let E be a real Banach space. A nonempty, closed, convex set P ⊂ E is said to be a cone provided the following conditions are satisfied: i if x ∈ P and λ ≥ 0, then λx ∈ P , ii if x ∈ P and −x ∈ P , then x 0. Lemma 2.2 see 20, 22 . Let P be a cone in a Banach...

This paper characterizes the possible blow-up of solutions for 3D magneto-hydrodynamics (MHD short) equations. We first establish some ϵ-regularity criteria in Lq,∞ spaces suitable weak solutions, and then together with an embedding theorem from Lp,∞ space into a Morrey type we characterize local behaviors near potential singular point. More precisely, show that if z0=(t0,x0) is point, any r>0 ...

Large time behavior of solutions to abstract differential equations is studied. The results give sufficient condition for the global existence of a solution to an abstract dynamical system (evolution problem), for this solution to be bounded, and for this solution to have a finite limit as t → ∞, in particular, sufficient conditions for this limit to be zero. The evolution problem is: u̇ = A(t)u...
