Geometric Realizations of the Multiplihedron and Its Complexification
نویسنده
چکیده
We realize Stasheff’s multiplihedron geometrically as the moduli space of stable quilted disks. This generalizes the geometric realization of the associahedron as the moduli space of stable disks. We also construct an algebraic variety that has the multiplihedron as its non-negative real part, and use it to define a notion of morphism of cohomological field theories.

Nonlinear energy harvesting through a multimodal electro-mechanical system
A semi-analytical method is used to illustrate the behavior of a multimodal nonlinear electromechanical system which is under base-excitation. System is considered as piezo-ceramic patches attached to a cantilever beam coupled to a resistive load. The cantilever beam is modeled as a nonlinear Timoshenko beam using Assumed Mode method and equations of motion are derived through Lagrange's equati...
متن کاملToeplitz Quantization and Asymptotic Expansions: Geometric Construction⋆
For a real symmetric domain GR/KR, with complexification GC/KC, we introduce the concept of “star-restriction” (a real analogue of the “star-products” for quantization of Kähler manifolds) and give a geometric construction of the GR-invariant differential operators yielding its asymptotic expansion.
متن کاملA new approach to microstructure optimization of solid oxide fuel cell electrodes
Designing optimal microstructures for solid oxide fuel cell (SOFC) electrodes is complicated due to the multitude of electro-chemo-physical phenomena taking place simultaneously that directly affect working conditions of a SOFC electrode and its performance. In this study, a new design paradigm is presented to obtain a balance between electrochemical sites in the form of triple phase boundary (...
متن کاملMarked tubes and the graph multiplihedron
Given a graph G , we construct a convex polytope whose face poset is based on marked subgraphs of G . Dubbed the graph multiplihedron, we provide a realization using integer coordinates. Not only does this yield a natural generalization of the multiplihedron, but features of this polytope appear in works related to quilted disks, bordered Riemann surfaces and operadic structures. Certain exampl...
متن کاملImproved logarithmic-geometric mean inequality and its application
In this short note, we present a refinement of the logarithmic-geometric mean inequality. As an application of our result, we obtain an operator inequality associated with geometric and logarithmic means.
