Cayley Graphs with an Infinite Heesch Number

We construct a 2-generated group Γ such that its Cayley graph possesses finite connected subsets with arbitrarily large finite Heesch number. Thus we obtain an example of a Cayley graph with an infinite Heesch number.

Two-Level Optimization Problems with Infinite Number of Convex Lower Level Constraints

‎This paper proposes a new form of optimization problem which is a two-level programming problem with infinitely many lower level constraints‎. ‎Firstly‎, ‎we consider some lower level constraint qualifications (CQs) for this problem‎. ‎Then‎, ‎under these CQs‎, ‎we derive formula for estimating the subdifferential of its valued function‎. ‎Finally‎, ‎we present some necessary optimality condit...

Gluing an Infinite Number of Instantons

This paper is one step toward infinite energy gauge theory and the geometry of infinite dimensional moduli spaces. We generalize a gluing construction in the usual Yang-Mills gauge theory to an “infinite energy” situation. We show that we can glue an infinite number of instantons, and that the resulting instantons have infinite energy in general. Moreover they have an infinite dimensional param...

Sturm-Liouville problems with an infinite number of interior singularities

The generalized Sturm-Liouville problems in this paper stem from the ideas of Christ Shubin and Stolz, based on introducing singularities at a countable number of regular points on the real line. This idea is generalized to the introduction of a countable number of regular or limitcircle singular points. These results are shown to link with the work of Everitt and Zettl concerned with operator ...

Cellular Automata with an Infinite Number of Subshift Attractors

The concept of an attractor is essential for understanding the dynamics of cellular automata. An attractor is defined as a limit set (intersection of forward images) of a nonempty clopen (closed and open) invariant set. Classification of cellular automata based on the system of their attractors has been considered in Hurley [1] or Kůrka [2]. The basic distinction is between cellular automata wh...
