Phase Transitions in Equilibrium and Non-Equilibrium Models on Some Topologies
Published 2016-03-01“…These are investigated on networks, like Apollonian (AN), Barabási–Albert (BA), small-worlds (SW), Voronoi–Delaunay (VD) and Erdös–Rényi (ER) random graphs. The review here is on phase transitions, critical points, exponents and universality classes that are compared to the results obtained for these models on regular square lattices (SL).…”

Polynomial Algorithm for Minimal (1,2)-Dominating Set in Networks
Published 2022-01-01“…We test the proposed algorithm in network models such as trees, geometric random graphs, random graphs and cubic graphs, and we show that the sets of nodes returned by the Minimal_12_Set are in general smaller than sets consisting of nodes chosen randomly.…”

Limit distributions of maximum vertex degree in a conditional configuration graph
Published 2018-06-01“…The degrees of the vertices are independent identically distributed random variables following the power-law distribution with positive parameter τ. We study the random graphs under the conditions that the sum of vertex degrees does not exceed n and the parameter τ is a random variable uniformly distributed on the interval [a,b], 1≤a<b<∞. …”

The Ramsey number of dense graphs
Published 2012“…We also investigate some related problems, such as the Ramsey number of graphs with t vertices and maximum degree pt and the Ramsey number of random graphs in G(t,p), that is, graphs on t vertices where each edge has been chosen independently with probability p.…”

Poisson approximation of subgraph counts in stochastic block models and a graphon model
Published 2016“…Small subgraph counts can be used as summary statistics for large random graphs. We use the Stein-Chen method to derive Poisson approximations for the distribution of the number of subgraphs in the stochastic block model which are isomorphic to some fixed graph. …”

Lower bounds for adiabatic quantum algorithms by quantum speed limits
Published 2023-09-01“…In particular, we analytically obtain lower bounds on adiabatic algorithms for finding k-clique in random graphs. Additionally, for a particular class of Hamiltonian, it is straightforward to prove the equivalence between our framework and the conventional approach based on spectral gap analysis.…”

Discrete curvature on graphs from the effective resistance
Published 2022“…Notably, we find a relation to a number of well-established discrete curvatures (Ollivier, Forman, combinatorial curvature) and show evidence for convergence to continuous curvature in the case of Euclidean random graphs. Being both efficient to approximate and highly amenable to theoretical analysis, these resistance curvatures have the potential to shed new light on the theory of discrete curvature and its many applications in mathematics, network science, data science and physics.…”

Entropic barriers as a reason for hardness in both classical and quantum algorithms
Published 2021-10-01“…We study both classical and quantum algorithms to solve a hard optimization problem, namely 3-XORSAT on 3-regular random graphs. By introducing a new quasi-greedy algorithm that is not allowed to jump over large energy barriers, we show that the problem hardness is mainly due to entropic barriers. …”

Resolution of ranking hierarchies in directed networks.
Published 2018-01-01“…To investigate the resolution of ranking hierarchies we introduce an ensemble of random graphs, the Ranked Stochastic Block Model. We find that agony may fail to identify hierarchies when the structure is not strong enough and the size of the classes is small with respect to the whole network. …”
