Semi-stream processing has become an emerging area of research in the field of data stream management. One common operation in semi-stream processing is joining a stream with disk-based master data using a join operator. This join operator typically works under limited main memory and this memory is generally not large enough to hold the whole disk-based master data. Recently, a number of semi-...

by Sagun Chanillo §1. Introduction: Let G denote a Lie group. We are concerned here with the initial value problem for the time dependent Schrödinger eqn., −iu t = ∆u, u| t=0 = f (x), x ∈ G (1.1) ∆ will denote the Laplace-Beltrami operator with respect to an appropriate G invariant metric. Our main aim is to obtain conditions on f which will guarantee that the solution u(x, t), vanishes identic...

The theory of anti-selfdual (ASD) Lagrangians –introduced in [7]– is developed further to allow for a variational resolution of non-linear PDEs of the form Λu+Au+ ∂φ(u)+ f = 0 where φ is a convex lower-semi-continuous function on a reflexive Banach space X , f ∈ X∗, A : D(A) ⊂ X → X∗ is a positive linear operator and where Λ :D(Λ)⊂X→X∗ is a non-linear operator that satisfies suitable continuity...
