This paper has been withdrawn by the authors due to some technical problems in the paper.

This paper has been withdrawn by the authors, due a crucial error in Sec. 3.

In the paper Phys. Lett. B614 (2005), 140-142, F. Nasseri shows that the values of the fine structure constant reduces due to the presence of a cosmic string. In this comment I want to point out that this conclusion is not completely…

The solution to the supersymmetric FCNC problem may not have a simple field theory interpretation. Here I advocate a possibility based on string selection rules. The requirement of non--trivial Yukawa structures restricts the form of the…

String theory has been the dominating research field in theoretical physics during the last decades. Despite the considerable time elapse, no new testable predictions have been derived by string theorists and it is understandable that…

A brief review of the motivation and the present status of Fractional Superstring is presented. Talk at ``Strings 93'', Berkeley, May 1993.

These lectures review some of the basic properties of $N=2$ superconformal field theories and the corresponding topological field theories. One of my basic aims is to show how the techniques of topological field theory can be used to…

These lectures give an introduction to the novel duality relating type IIB string theory in a maximally supersymmetric plane-wave background to N=4, d=4, U(N) Super Yang-Mills theory in a particular large N and large R-charge limit due to…

Lectures presented at the Spring School, Trieste, Italy 1993.

This paper was withdrawn by the author. It turns out that similar ideas have been presented before. The author apologizes.

This manuscript has been withdrawn because of significant overlap with an existing paper (Szabolcs Varga and Istvan Szalai, "Phase diagrams of binary mixtures of hard rods in an external orientational field", Phys. Chem. Chem. Phys.,…

Controversies arise when specialists disagree on some particular issue. This normally occurs in any scientific brunch. We analyze some controversies, which have a good cause in Special Relativity. The paper does not question Special…

This comment is written on the article by Hiroyasu Koizumi, in which an alternative theory of superconductivity is proposed. No Joule heating is predicted in this theory unlike the conventional BCS-London theory of superconductivity. The…

This is a 20-year old review on singularities and singularity theorems. The main reason to submit it now is -apart from increasing its availability- to correct a very strange error that appears in the journal's online version: it contains…

This paper has been withdrawn by the authors, due to inappropriate discussions in Discussions.

As was shown by Aharony, Hanany and Kol and independently by Sen, type IIB string theory admits configurations where strings of different charges (p_i, q_i) form so-called string networks. We argue that these networks blow up into…

This paper has been removed by arXiv administrators because it plagiarizes gr-qc/0410004, gr-qc/0603075, and others. This paper also has excessive overlap with the following papers also written by the authors or their collaborators:…

The status of string theory is reviewed, and major recent developments - especially those in going beyond perturbation theory in the string theory and quantum field theory frameworks - are discussed. This analysis helps better understand…

This paper has been submitted to Science. It summarizes the experimental evidence for (and against) the interlayer theory. It was delayed in posting by clerical error.

In these lectures we review the quantum physics of large Schwarzschild black holes. Hawking's information paradox, the theory of the stretched horizon and the principle of black hole complementarity are covered. We then discuss how the…
