Strong products of Kneser graphs
Discrete Mathematics, 1994 For a (simple, undirected) graph \(G = (V(G), E(G))\), let \(\chi(G)\) and \(\omega(G)\) denote the chromatic number and the clique number, respectively. A subgraph \(H\) of \(G\) is a retract of \(G\) iff there is an edge-preserving map \(h : V(G) \to V(H)\) with \(h(x) = x\) for all \(x \in V(H)\).

Zero-sum flow number of categorical and strong product of graphs [PDF]
Transactions on Combinatorics, 2020 A zero-sum flow is an assignment of nonzero integers to the edges such that the sum of the values of all edges incident with each vertex is zero, and we call it a zero-sum $k$-flow if the absolute values of edges are less than $k$. We define the zero-sum

European Journal of CombinatoricsRecent results show that several important graph classes can be embedded as subgraphs of strong products of simpler graphs classes (paths, small cliques, or graphs of bounded treewidth). This paper develops general techniques to bound the chromatic number (and its popular variants, such as fractional, clustered, or defective chromatic number) of the ...

Cosmological particle production at strong coupling [PDF]
Journal of High Energy Physics, 2015 We study the dynamics of a strongly-coupled quantum field theory in a cosmological spacetime using the holographic AdS/CFT correspondence. Specifically we consider a confining gauge theory in an expanding FRW universe and track the evolution of the stress-energy tensor during a period of expansion, varying the initial temperature as well as the rate ...

Strong expansions of products and products in strong shape
Topology and its Applications, 2004 The paper is devoted to the study of strong expansions and strong shape of Cartesian products of topological spaces. If the Cartesian product of two spaces X and Y admits a strong expansion, which is the Cartesian product of strong polyhedral expansions of these spaces, then XxY is the product in the strong shape category.

Strong Convergence in a Product Space [PDF]
Proceedings of the American Mathematical Society, 1962 The purpose of this note is to present a certain necessary and sufficient condition for strong convergence in Lp over a product space. This result is formulated as Theorem 1 below. Theorem 1 includes as a special case a well-known compactness condition of M. Riesz, which we state in slightly different form as Theorem 2.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...
