Agreement tests are a generalization of low degree tests that capture a local-to-global phenomenon, which forms the combinatorial backbone of most PCP constructions. In an agreement test, a function is given by an ensemble of local restrictions.

Preserving the utility of published datasets while simultaneously providing provable privacy guarantees is a well-known challenge.

The complexity of Iterated Matrix Multiplication is a central theme in Computational Complexity theory, as the problem is closely related to the problem of separating various complexity classes within $P$.

Entanglement is an important resource in quantum communication protocols and as such the problem of turning a preshared entangled state between two parties Alice and Bob into a Bell state has been studied extensively.

The standard hard-core model on a locally finite graph describes a family of Gibbs specifications, parameterized by the so-called activity parameter. An important problem is to determine when the model has a unique Gibbs measure and when it exhib

We study the problem of finding an Euler tour in an undirected graph $G$ in the W-Streaming model with $\mathcal{O}(n\,\textrm{polylog}(n))$ RAM, where $n$ resp.\ $m$ is the number of nodes resp.\ edges of $G$. Our main result is the first one pa

Propositional proof complexity is the study of the resources that are needed to prove formulas in propositional logic.

We would discuss the lower bound on the joint entropy of pairwise independent random variables (X_1, ... , X_n) by Lazlo Babai (2013).

The notion of control can be thought of as the process of selection of a policy to influence the dynamics of a system in order to achieve a desired objective.
