The Riemann problem on a ray for generalized analytic functions with a singular line [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2023 In this paper, we study an inhomogeneous Riemann boundary value problem with a finite index and a boundary condition on a ray for a generalized Cauchy – Riemann equation with a singular coefficient.

Hilbert boundary value problem for generalized analytic functions with a singular line [PDF]
E3S Web of Conferences, 2021 In this paper, we study an inhomogeneous Hilbert boundary value problem with a finite index and a boundary condition on a circle for a generalized Cauchy-Riemann equation with a singular coefficient.

The Distinguishing Index of Infinite Graphs [PDF]
The Electronic Journal of Combinatorics, 2015 The distinguishing index $D^\prime(G)$ of a graph $G$ is the least cardinal $d$ such that $G$ has an edge colouring with $d$ colours that is only preserved by the trivial automorphism. This is similar to the notion of the distinguishing number $D(G)$ of a graph $G$, which is defined with respect to vertex colourings.We derive several bounds for ...

ON THE REPETITIVITY INDEX OF INFINITE WORDS [PDF]
International Journal of Algebra and Computation, 2009 With any infinite word w we associate a function, called the repetitivity index, giving, for any non-negative integer n, the minimal distance between any two occurrences of identical factors of length n in w. Some properties of the repetitivity index are studied concerning, in particular, periodic words, synchronized sequences, smooth words.

A COMMENT ON JONES INCLUSIONS WITH INFINITE INDEX [PDF]
Reviews in Mathematical Physics, 1995 Given an irreducible inclusion of infinite von-Neumann-algebras [Formula: see text] together with a conditional expectation [Formula: see text] such that the inclusion has depth 2, we show quite explicitly how [Formula: see text] can be viewed as the fixed-point algebra of [Formula: see text] w.r.t.

Groups in which Every Subgroup of Infinite Rank is Nearly Permutable [PDF]
Advances in Group Theory and Applications, 2017 In this paper, the structure of locally finite groups of infinite rank whose subgroups of infinite rank have finite index in a permutable subgroup is investigated.

On the Graovac-Pisanski index [PDF]
Kragujevac Journal of Science, 2017 The Graovac-Pisanski index (GP index) is an algebraic approach for generalizing the Wiener index. In this paper, we compute the difference between the Wiener and GP indices for an infinite family of polyhedral graphs.

Hamilton Connectivity of Convex Polytopes with Applications to Their Detour Index
Complexity, 2021 A connected graph is called Hamilton-connected if there exists a Hamiltonian path between any pair of its vertices. Determining whether a graph is Hamilton-connected is an NP-complete problem.

A Note on a necessary condition for optimality [PDF]
Modeling, Identification and Control, 1990 A necessary condition is derived for the optimality of a linear multivariable feedback control system with respect to a quadratic performance index of infinite settling time.
