We extend the ideas of Friedman and Qin [5] to find the wall-crossing formulae for the Donaldson invariants of algebraic surfaces with pg = 0, q > 0 and anticanonical divisor −K effective, for any wall ζ with lζ = 1 4 (ζ − p1) being 0 or 1.

We show how methods from K-theory of operator algebras can be applied in a completely algebraic setting to define a bivariant, M∞-stable, homotopy-invariant, excisive Ktheory of algebras over a fixed unital ground ring H, (A, B) 7→ kk∗(A, B), which is universal in the sense that it maps uniquely to any other such theory. It turns out kk is related to C. Weibel’s homotopy algebraic K-theory, KH....

Optical owmay be effectively employed as a subtask of video segmentation by propagating the labels of an initial segmented frame throughout a contigious subset of the frames in the video. Commonphenomena in videos such as occlusion and disocclusion are frequent causes for unreliable optical ow which then cannot be used in the classi cation of these ambiguous local regions. is de ciency calls fo...

Capital Inflows , Liquidity and Bubbles Guillermo

Policymakers in Emerging Market economies (EMs) are facing a serious dilemma: while their economies are currently benefiting from a surge of capital inflows, they fear a replay of the 1990s and early 2000s when their economies underwent costly Sudden Stops (of capital inflows). A serious concern is that a capital‐inflow episode could give rise to "bubbles," i.e., an artificial or transitory inc...
