The set of homology cobordisms from a surface to itself with markings of their boundaries has a natural monoid structure. To investigate the structure of this monoid, we define and study its Magnus representation and Reidemeister torsion invariants by generalizing Kirk-Livingston-Wang’s argument over the Gassner representation of string links. Moreover, by applying Cochran and Harvey’s framewor...

We define new higher-order Alexander modules An(C) and higherorder degrees δn(C) which are invariants of the algebraic planar curve C. These come from analyzing the module structure of the homology of certain solvable covers of the complement of the curve C. These invariants are in the spirit of those developed by T. Cochran in [2] and S. Harvey in [7] and [8], which were used to study knots, 3...

Introduction: This study was carried out in order to compare mineral trioxide aggregate (MTA) and dycal in dog’s teeth as pulp capping agents. Methods: After general and local anesthesia forty-two teeth of three dogs were used. In each tooth a class V cavity was prepared and the pulp was exposed using No.1 round bur. Then the exposed area was capped using either MTA or calcium hydroxide and the...
