Stochastic Unsplittable Flows

We consider the stochastic unsplittable flow problem: given a graph with edge-capacities, k source-sink pairs with each pair {sj , tj} having a size Sj and value vj , the goal is to route the pairs unsplittably while respecting edge capacities to maximize the total value of the routed pairs. However, the size Sj is a random variable and is revealed only after we decide to route pair j. Which pa...

Application to Stochastic Flows

We review several competing chaining methods to estimate the supremum, the diameter of the range or the modulus of continuity of a stochastic process in terms of tail bounds of their two-dimensional distributions. Then we show how they can be applied to obtain upper bounds for the growth of bounded sets under the action of a stochastic flow.

Stochastic flows with reflection

Flows generated by SDEs in Euclidean space is a well-studied topic nowadays. It is well known for example (cf. [1] and ref. therein) that if the coefficients of SDE are Liphitzian then the SDE generates a flow of homeomorphisms, if coefficients are of the class C then SDE generates C-flow of diffeomorphisms, equations for derivatives are obtained by formal differentiation of the SDE etc. Note t...

Nonhomeomorphic conjugates of connected Shimura varieties

We show that conjugation by an automorphism of C may change the topological fundamental group of a locally symmetric variety over C. As a consequence, we obtain a large class of algebraic varieties defined over number fields with the property that different embeddings of the number field into C give complex varieties with nonisomorphic fundamental groups. Let V be an algebraic variety over C, a...

Stochastic flows on metric graphs

We study a simple stochastic differential equation (SDE) driven by one Brownian motion on a general oriented metric graph whose solutions are stochastic flows of kernels. Under some conditions, we describe the laws of all solutions. This work is a natural continuation of [17, 8, 10] where some particular metric graphs were considered.
