We discuss noncommutative solitons on a noncommutative torus and their application to tachyon condensation. In the large B limit, they can be exactly described by the Powers-Rieffel projectionâ€¦ (More)

We define a homotopy algebra associated to classical open-closed strings. We call it an open-closed homotopy algebra (OCHA). It is inspired by Zwiebachâ€™s open-closed string field theory and also isâ€¦ (More)

We discuss general properties of A âˆž-algebras and their applications to the theory of open strings. The properties of cyclicity for A âˆž-algebras are examined in detail. We prove the decompositionâ€¦ (More)

We discuss general properties of classical string field theories with symmetric vertices in the context of deformation theory. For a given conformal background there are many string field theoriesâ€¦ (More)

It is known that the physics of open strings on a D2-brane on a two-torus is realized from the viewpoint of deformation quantization in the Seiberg-Witten limit. We study its T-dual theory, i.e.â€¦ (More)

In this paper we discuss various aspects of open-closed homotopy algebras (OCHAs) presented in our previous paper, inspired by Zwiebachâ€™s open-closed string field theory, but that first paperâ€¦ (More)

Taste enhancing effects of sodium saccharin (Sac) on responses to particular sweet-tasting D-amino acids were found during the recording of mouse chorda tympani nerve responses to various tasteâ€¦ (More)

Homological mirror symmetry is a conjecture that a category constructed in the A-model and a category constructed in the B-model are equivalent in some sense. We construct a cyclic differentialâ€¦ (More)

This paper is concerned with nonlinear model reduction for electro-mechanical systems described by port-Hamiltonian formulae. A novel weighted balanced realization and model reduction procedure isâ€¦ (More)

We construct explicitly noncommutative deformations of categories of holomorphic line bundles over higher dimensional tori. Our basic tools are Heisenberg modules over noncommutative tori andâ€¦ (More)
