In this paper we propose a new, more appropriate definition of regular and indeterminate strings. A string is one that “isomorphic” to whose entries all consist single letter, but which nevertheless may itself include containing multiple letters. not said be indeterminate. We begin by proposing new model for the representation strings, or indeterminate, then go on describe linear time algorithm...

We consider the possible existence of gravitationally bound stringlike objects in framework generalized hybrid metric-Palatini gravity theory, which gravitational action is represented by an arbitrary function Ricci and Palatini scalars, respectively. The theory admits equivalent scalar-tensor representation terms two independent scalar fields. Assuming cylindrical symmetry, boost invariance me...

A picture is de ned to be ambiguous if there exists more than one di erent reconstructed picture from its representation In this paper we rst give an ambiguous case based on the adaptive D H string representation Next we show how to avoid the ambiguous cases

In this paper we present a model transformation from a visual representation (VisualOCL) of the Object Constraint Language (OCL) to the textual one using graph transformation. Starting from VisualOCL diagrams, we show how their underlying abstract syntax can be modeled by typed attributed graphs and converted into an OCL string representation using graph transformation rules.

A string with many repetitions can be represented compactly by replacing h-fold contiguous repetitions of a string r with (r)h. We present a compact representation, which we call a repetition representation (of a string) or RRS, by which a set of disjoint or nested tandem arrays can be compacted. In this paper, we study the problem of finding aminimum RRS or MRRS,where the size of an RRS is def...

Nonabelian gauge theories are the building blocks of the field-theoretical description of fundamental interactions. It is therefore essential to achieve a deep understanding of their physical content and a better quantitative knowledge of their testable predictions. It is widely believed that nonabelian gauge theories admit a reinterpretation in terms of effective strings; describing their prop...

Making use of the duality transformation, we derive in the Londons' limit of the Abelian Higgs Model string representation for the 't Hooft loop average, which yields the values of two coefficient functions parametrizing the bilocal correlator of monopole field strength tensors. The asymptotic bahaviours of these functions agree with the ones obtained within the Method of Vacuum Correlators in ...
