The eigenvalues and energy of integral circulant graphs [PDF]
Transactions on Combinatorics, 2012 A graph is called textit{circulant} if it is a Cayley graph on acyclic group, i.e. its adjacency matrix is circulant. Let $D$ be aset of positive, proper divisors of the integer $n>1$.

Transactions of the London Mathematical Society, Volume 5, Issue 1, Page 132-183, December 2018., 2018 Abstract The richly developed theory of complex manifolds plays important roles in our understanding of holomorphic functions in several complex variables. It is natural to consider manifolds that will play similar roles in the theory of holomorphic functions in several non‐commuting variables.

Functions of self‐adjoint operators in ideals of compact operators
Journal of the London Mathematical Society, Volume 95, Issue 1, Page 157-176, February 2017., 2017 Abstract For self‐adjoint operators A,B, a bounded operator J, and a function f:R→C, we obtain bounds in quasi‐normed ideals of compact operators for the difference f(A)J−Jf(B) in terms of the operator AJ−JB. The focus is on functions f that are smooth everywhere except for finitely many points. A typical example is the function f(t)=|t|γ with γ∈(0,1).

Generalized covariance‐based inference for models set‐identified from independence restrictions
Journal of Time Series Analysis, Volume 46, Issue 2, Page 300-324, March 2025.This article develops statistical inference methods for a class of set‐identified models, where the errors are known functions of observations and the parameters satisfy either serial or/and cross‐sectional independence conditions. This class of models includes the independent component analysis (ICA), Structural Vector Autoregressive (SVAR), and multi‐

Advances in Mathematical Physics, Volume 2017, Issue 1, 2017., 2017 This paper gives an introduction to certain classical physical theories described in the context of locally Minkowskian causal structures (LMCSs). For simplicity of exposition we consider LMCSs which have locally Euclidean topology (i.e., are manifolds) and hence are Möbius structures.

Open String Renormalization Group Flow as a Field Theory
Fortschritte der Physik, Volume 72, Issue 11, November 2024.Abstract This article shows that the integral flow‐lines of the RG‐flow of open string theory can be interpreted as the solitons of a Hořova–Lifshitz sigma‐model of open membranes. The authors argue that the effective background description of this model implies the g‐theorem of open string theory.

Self‐Adjoint Extension and Spectral Theory of a Linear Relation in a Hilbert Space
International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014 The aim of this paper is to develop the conditions for a symmetric relation in a Hilbert space ℋ to have self‐adjoint extensions in terms of defect indices and discuss some spectral theory of such linear relation.

Genuinely nonabelian partial difference sets
Journal of Combinatorial Designs, Volume 32, Issue 7, Page 351-370, July 2024.Abstract Strongly regular graphs (SRGs) provide a fertile area of exploration in algebraic combinatorics, integrating techniques in graph theory, linear algebra, group theory, finite fields, finite geometry, and number theory. Of particular interest are those SRGs with a large automorphism group.

Bounds on the Distance Energy and the Distance Estrada Index of Strongly Quotient Graphs
Journal of Applied Mathematics, Volume 2013, Issue 1, 2013., 2013 The notion of strongly quotient graph (SQG) was introduced by Adiga et al. (2007). In this paper, we obtain some better results for the distance energy and the distance Estrada index of any connected strongly quotient graph (CSQG) as well as some relations between the distance Estrada index and the distance energy.
