If Φ is a small class of weights we can define, as we did for J -Colim, a2-category Φ- Colim of small categories with chosen Φ-colimits, functors preserving these strictly, and

There is a stable limit cycle between the borders of the stability domain but the fix points are stable only along the continuous line between the bifurcation points indicated

As far as local conditions at infinity are concerned, it is shown that at energy zero the Dirac equation without mass term has no non-trivial L 2 -solutions at infinity for

We present sufficient conditions for the existence of solutions to Neu- mann and periodic boundary-value problems for some class of quasilinear ordinary differential equations.. We

For further analysis of the effects of seasonality, three chaotic attractors as well as a Poincar´e section the Poincar´e section is a classical technique for analyzing dynamic

It leads to simple purely geometric criteria of boundary maximality which bear hyperbolic nature and allow us to identify the Poisson boundary with natural topological boundaries

We formalize and extend this remark in Theorem 7.4 below which shows that the spectral flow of the odd signature operator coupled to a path of flat connections on a manifold
