Topological open/closed string dualities: matrix models and wave functions

Journal of High Energy Physics, 2019
We sharpen the duality between open and closed topological string partition functions for topological gravity coupled to matter. The closed string partition function is a generalized Kontsevich matrix model in the large dimension limit.

Trees with Certain Locating-chromatic Number

Journal of Mathematical and Fundamental Sciences, 2016
The locating-chromatic number of a graph G can be defined as the cardinality of a minimum resolving partition of the vertex set V(G) such that all vertices have distinct coordinates with respect to this partition and every two adjacent vertices in G are ...

Semi-pointed partition posets and Species

, 2015
We define semi-pointed partition posets, which are a generalisation of partition posets and show that they are Cohen-Macaulay. We then use multichains to compute the dimension and the character for the action of the symmetric groups on their homology. We

Adaptive Clustering through Semidefinite Programming

, 2017
We analyze the clustering problem through a flexible probabilistic model that aims to identify an optimal partition on the sample X 1 , ..., X n. We perform exact clustering with high probability using a convex semidefinite estimator that interprets as a

On the Constant Partition Dimension of Some Generalized Families of Toeplitz Graph

Journal of Mathematics
The use of graph theory is prevalent in the field of network design, whereby it finds utility in several domains such as the development of integrated circuits, communication networks, and transportation systems. The comprehension of partition dimensions

All Graphs of Order n with Distinguishing Number n−1 or n − 2

Theory and Applications of Graphs
Let G be a simple connected graph. The distinguishing number of G, denoted by D(G), is the least integer d such that G has a vertex d-labeling preserved only by the trivial automorphism.

Two-dimensional interpolation using a cell-based searching procedure

, 2014
In this paper we present an efficient algorithm for bivariate interpolation, which is based on the use of the partition of unity method for constructing a global interpolant.

On Partition Dimension and Domination of Abid-Waheed 〖(AW)〗_r^4 Graph

مجلة بغداد للعلوم
A graph denoted by H, which has a simple link between its vertices, possesses the set of vertices V(H) . Given a graph,  a set that is dominant, is a subset of vertex set  such that any vertex outside of  is close to at least one vertex inside of .
