Gravitational and axial anomalies for generalized Euclidean Taub-NUT metrics [PDF]

, 2004
The gravitational anomalies are investigated for generalized Euclidean Taub-NUT metrics which admit hidden symmetries analogous to the Runge-Lenz vector of the Kepler-type problem. In order to evaluate the axial anomalies, the index of the Dirac operator

Reflexivity and order properties of scalar-type spectral operators in locally convex spaces [PDF]

Transactions of the American Mathematical Society, 1986
One of the principal results of the paper is that each scalar-type spectral operator in the quasicomplete locally convex space X X is reflexive. The paper also studies in detail the relation between the theory of equicontinuous spectral measures in locally convex spaces and the order properties of equicontinuous Bade complete Boolean ...

Curvature in Noncommutative Geometry

, 2020
Our understanding of the notion of curvature in a noncommutative setting has progressed substantially in the past ten years. This new episode in noncommutative geometry started when a Gauss-Bonnet theorem was proved by Connes and Tretkoff for a curved ...

On Boolean algebras of projections and scalar-type spectral operators [PDF]

Proceedings of the American Mathematical Society, 1983
It is shown that the weakly closed operator algebra generated by an equicontinuous σ \sigma -complete Boolean algebra of projections on a quasi-complete locally convex space consists entirely of scalar-type operators. This extends W. Badé’s well-known theorem that the same assertion is valid for Banach spaces; however, the technique of

Bounds for OPE coefficients on the Regge trajectory

Journal of High Energy Physics, 2017
We consider the Regge limit of the CFT correlation functions JJOO $$ \left\langle \mathcal{JJOO}\right\rangle $$ and T T O O $$ \left\langle TT\mathcal{O}\mathcal{O}\right\rangle $$ , where J $$ \mathcal{J} $$ is a vector current, T is the stress tensor ...

On the Chern-Gauss-Bonnet Theorem and Conformally Twisted Spectral Triples for $C^*$-Dynamical Systems [PDF]

, 2016
The analog of the Chern-Gauss-Bonnet theorem is studied for a $C^*$-dynamical system consisting of a $C^*$-algebra $A$ equipped with an ergodic action of a compact Lie group $G$. The structure of the Lie algebra $\mathfrak{g}$ of $G$ is used to interpret

The Spectral Zeta Function for Laplace Operators on Warped Product Manifolds of the type $I\times_{f} N$

, 2011
In this work we study the spectral zeta function associated with the Laplace operator acting on scalar functions defined on a warped product of manifolds of the type $I\times_{f} N$ where $I$ is an interval of the real line and $N$ is a compact, $d ...

ON REFLEXIVITY OF SCALAR-TYPE SPECTRAL OPERATORS

Demonstratio Mathematica, 1999
\(X\) is said to be a locally convex \(C(K)\)-module if the bilinear mapping \(C(K)\times X\to X:(a, x)\to ax\) satisfies the following conditions: (i) 1. \(x= x\) for all \(x\) in \(X\), (ii) \((a,b)x= a.(bx)\) \((a\in C(K),b\in C(K),x\in X)\), (iii) the bilinear mapping is separately continuous. Here \(K\) is a compact Hausdorff space.

Reanalysis of the $Y(3940)$, $Y(4140)$, $Z_c(4020)$, $Z_c(4025)$ and $Z_b(10650)$ as molecular states with QCD sum rules [PDF]

In this article, we calculate the contributions of the vacuum condensates up to dimension-10 in the operator product expansion, and study the $J^{PC}=0^{++}$, $1^{+-}$, $2^{++}$ $D^*\bar{D}^*$, $D_s^*\bar{D}_s^*$, $B^*\bar{B}^*$, $B_s^*\bar{B}_s ...

Operator Lipschitz functions on Banach spaces

, 2016
Let $X$, $Y$ be Banach spaces and let $\mathcal{L}(X,Y)$ be the space of bounded linear operators from $X$ to $Y$. We develop the theory of double operator integrals on $\mathcal{L}(X,Y)$ and apply this theory to obtain commutator estimates of the form $\
