We revisit the classical singular control problem of minimizing running and controlling costs. Existing studies have shown the optimality of a barrier strategy when driven by Brownian motion or Lé…
We show that the properties of being rationally K-stable passes from the fibres of a continuous C(X) -algebra to the ambient algebra, under the assumption that the underlying space X is compact,…
Homotopy theory folklore tells us that the sheaf defining the cohomology theory Tmf of topological modular forms is unique up to homotopy. Here we provide a proof of this fact, although we claim no…
We consider a subshift of finite type on q symbols with a union of t cylinders based at words of identical length p as the hole. We explore the relationship between the escape rate into the hole an…
We prove an incidence result counting the k-rich δ-tubes induced by a well-spaced set of δ-atoms. Our result coincides with the bound that would be heuristically predicted by the Szemerédi–Tro…
We study the symplectic leaves of the subvariety of fixed points of an automorphism of a Calogero–Moser space induced by an element of finite order of the normalizer of the associated complex ref…
We develop new higher-order asymptotic techniques for the Gaussian maximum likelihood estimator in a spatial panel data model, with fixed effects, time-varying covariates, and spatially correlated …
In this paper, we show that Leavitt path algebras of weighted graphs and Leavitt path algebras of separated graphs are intimately related. We prove that any Leavitt path algebra L(E,ω) of a ro…
We develop a dynamic model where a principal contracts with an agent to operate a firm. The agent, protected by limited liability, trades privately a market portfolio to hedge market risk in his co…
Using the setting of funds of hedge funds (FoFs), we show that prime brokers (PBs) facilitate investors’ search for informed hedge fund managers. We find that FoFs exhibit PB bias, a disproportio…
