cosmological models with an su ( 2 ) yang - mills field are studied. for a specific model with a minimally coupled yang - mills lagrangian, which includes an arbitrary function of the second - order term and a fourth - order term, a corresponding reconstruction program is proposed. it is shown that the model with minim... | arxiv:1201.4302 |
the weighted $ k $ - center problem in graphs is a classical facility location problem where we place $ k $ centers on the graph, which minimize the maximum weighted distance of a vertex to its nearest center. we study this problem when the underlying graph is a cactus with $ n $ vertices and present an $ o ( n \ log ^... | arxiv:2303.17204 |
let $ v ( k, \ lambda ) $ be the maximum number of vertices of a connected $ k $ - regular graph with second largest eigenvalue at most $ \ lambda $. the alon - boppana theorem implies that $ v ( k, \ lambda ) $ is finite when $ k > \ frac { \ lambda ^ 2 + 4 } { 4 } $. in this paper, we show that for fixed $ \ lambda \... | arxiv:1809.01888 |
