TL;DR: In this article, the authors studied aspects of the refining and shifting properties of the 3D MacMahon function C3(q) used in topological string theory and BKP hierarchy.
Abstract: We study aspects of the refining and shifting properties of the 3d MacMahon function C3(q) used in topological string theory and BKP hierarchy. We derive the explicit expressions of the shifted topological vertex Sλμν(q) and its refined version Tλμν(q,t). These vertices complete results in literature.

TL;DR: In this paper, the homology of a 2-colored dioperad of decorated Riemann surfaces, relevant to open-closed string field theory, is computed and the structure described is realized in an open closed setting of string topology via an action at the level of topological spaces.

TL;DR: In this article, the authors analyze the topological nature of c = 1 string theory at the self-dual radius and find that it admits two distinct topological field theory structures characterized by two different puncture operators.

TL;DR: In this article, it was shown that with the help of a general BRST symmetry, different theories in three dimensions can be connected through a fundamental topological field theory related to the classical limit of the Chern-Simons model.

TL;DR: In this paper, a series of results pertinent to dynamics of the low-dimensional geometrical objects of spacetime are presented, including the D0-brane recoil and annihilation, local recoil of D1-branes, and D-and F-string loop mixing.
Abstract: Modern string theory naturally gives rise to an assortment of dynamical geometrical objects of various dimensions (collectively referred to as "branes") embedded into spacetime. The aim of this thesis is to present a series of results (of varying novelty and rigor) pertinent to dynamics of the low-dimensional geometrical objects of this kind. The processes considered are the D0-brane recoil and annihilation, "local recoil" of D1-branes (which is a peculiar effect manifested by one-dimensional topological defects in response to an impact, and closely related to soliton recoil), and D- and F-string loop mixing. Apart from the practical relevance within the formalism of string theory, such considerations are worthwhile in that the quantum dynamics of the geometrical objects involved is complex enough to be interesting, yet simple enough to be tractable. Furthermore, some of the results derived here within the string theory formalism may give valuable insights into the dynamics of low-dimensional field-theoretical topological defects.
