3-Tuple Total Domination Number of Rook’s Graphs

Discussiones Mathematicae Graph Theory, 2022
A k-tuple total dominating set (kTDS) of a graph G is a set S of vertices in which every vertex in G is adjacent to at least k vertices in S. The minimum size of a kTDS is called the k-tuple total dominating number and it is denoted by γ×k,t(G).

Renormalization of Non-Commutative Phi^4_4 Field Theory in x Space

, 2005
In this paper we provide a new proof that the Grosse-Wulkenhaar non-commutative scalar Phi^4_4 theory is renormalizable to all orders in perturbation theory, and extend it to more general models with covariant derivatives.

An Alternative Approach to Spontaneous Photon Triplets Generation

Advanced Physics Research, EarlyView.
Day by day, communication and computing technologies are progressing at a lightning speed, which is particularly true of the quantum version of these technologies (QIST). Increasingly, these technologies are emerging from unusual and sometimes bewildering quantum optical effects, which are based on exotic quantum physical theories.

The spaces OM and OC are ultrabornological a new proof

International Journal of Mathematics and Mathematical Sciences, 1985
In [1] Laurent Schwartz introduced the spaces 𝒪M and 𝒪′C of multiplication and convolution operators on temperate distributions. Then in [2] Alexandre Grothendieck used tensor products to prove that both 𝒪M and 𝒪′C are bornological.

Parabolic methods for the construction of spacelike slices of prescribed mean curvature in cosmological spacetimes [PDF]

, 1999
Spacelike hypersurfaces of prescribed mean curvature in cosmological space times are constructed as asymptotic limits of a geometric evolution equation. In particular, an alternative, constructive proof is given for the existence of maximal and constant ...

Constructive Dimension and Turing Degrees

, 2009
This paper examines the constructive Hausdorff and packing dimensions of Turing degrees. The main result is that every infinite sequence S with constructive Hausdorff dimension dim_H(S) and constructive packing dimension dim_P(S) is Turing equivalent to ...

Restricted Tweedie stochastic block models

Canadian Journal of Statistics, EarlyView.
Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.

Rotating periodic solutions for second order systems with Hartman-type nonlinearity

Boundary Value Problems, 2018
In this paper, by a constructive proof based on the homotopy continuation method, we prove that the second order system x″=g(t,x) $x''=g(t,x)$ admits rotating periodic solutions with form u(t+T)=Qu(t) $u(t+T)=Qu(t)$ for any orthogonal matrix Q when the ...
