Zariski decompositions of numerical cycle classes
Mihai Fulger, Brian Lehmann
We construct a Zariski decomposition for cycle classes of arbitrary codimension. This decomposition is an analogue of well-known constructions for divisors. Examples illustrate how…

Asymptotic behavior of the dimension of the Chow variety
Brian Lehmann
We analyze the asymptotics of the dimension of components of the Chow variety as degree increases. By analogy with the divisor case, the main goal is to relate the asymptotic behav…
