Interface evolution in bistable spatial models: a global approach
Thomas HUGHES (Université de Bath)
We consider spatial stochastic population models exhibiting bistability. In such models, narrow interfaces tend to form between regions dominated by one of the two stable [...]

Selmer groups, p-adic L-functions and Euler Systems: A Unified Framework
Marco Sangiovanni Vincentelli (Princeton)
Selmer groups are key invariants attached to p-adic Galois representations. The Bloch—Kato conjecture predicts a precise relationship between the size of certain Selmer groups and [...]

A pointwise ergodic theorem for non-commuting ℝ-actions
Rongzhong Xiao (I2M & University of Science and Technology of China)
In 2023, under some mild conditions, Frantzikinakis and Host proved a mean ergodic theorem without any commutativity. Later, Frantzikinakis built its continuous-time anologue without any [...]
