Christian Bick @bickmath.bsky.social · 15/12/2025Simply: The dynamics themselves do not go away, but making things more generic helps understand how they organize the dynamics more generally. 010
Christian Bick @bickmath.bsky.social · 15/12/2025Not the interactions themselves. Sometimes they are just too special and give rise to extra symmetries. 100
Christian Bick @bickmath.bsky.social · 15/12/2025Let's break some structures imposed by higher-order interactions! We compute how things deform and what remains when continuous symmetries are broken.

Christian Bick @bickmath.bsky.social · 28/10/2025The nice summary "Reducing the dimensions of adaptive networks" for a broader audience was published alongside the paper at doi.org/10.1063/10.0...doi.orgReducing the dimensions of adaptive networksFramework for decreasing the dimensionality of complex systems facilitates analysis of complexity. 110
Christian Bick @bickmath.bsky.social · 28/10/2025This motivates new mathematical insights into the multiple time scale dynamics of adaptive networks. And opens up questions how constraints and adaptive dependency is realized in real world adaptive networks. 110
Christian Bick @bickmath.bsky.social · 28/10/2025We introduce constraints to the adaptive dynamics as a way to reduce dimensionality. These may be intrinsic, for example, if the adaptation rule is nondirectional. Or they may be forced by a homeostasis mechanism. 110
Christian Bick @bickmath.bsky.social · 28/10/2025Adaptivity is a crucial ingredient of many networked systems, but a key issue is their high-dimensionality. A dense network of N nodes has O(N^2) adaptive connections. 110
