Holomorphic anomalies, fourfolds and fluxes

Journal of High Energy Physics, 2022
We investigate holomorphic anomalies of partition functions underlying string compactifications on Calabi-Yau fourfolds with background fluxes. For elliptic fourfolds the partition functions have an alternative interpretation as elliptic genera of N = 1 ...

Characteristic Polynomial and Eigenproblem of Triangular Matrix over Interval Min-Plus Algebra

JTAM (Jurnal Teori dan Aplikasi Matematika)
A min-plus algebra is a linear algebra over the semiring R_ε', equipped with the operations “"⊕'=min" ” and “⊗=+”. In min-plus algebra, there is the concept of characteristic polynomial obtained from permanent of matrix.

Analog Classification of Human Hand Gestures Exploiting Dendritic Integration With an Organic Artificial Soma

Advanced Functional Materials, EarlyView.
An organic neuromorphic architecture for the classification of human motor behavior is presented and validated. It performs somatic integration by linearly combining the activity from three muscles. An investigation of synaptic weights is presented and discussed in relationship with the classification performance.

Algebras Generated by Reciprocals of Linear Forms

Journal of Algebra, 2002
Let $Δ$ be a finite set of nonzero linear forms in several variables with coefficients in a field $\mathbf K$ of characteristic zero. Consider the $\mathbf K$-algebra $C(Δ)$ of rational functions generated by $\{1/α\mid α\in Δ\}$. Then the ring $\partial(V)$ of differential operators with constant coefficients naturally acts on $C(Δ)$.

Dual spaces and bilinear forms in supertropical linear algebra [PDF]

Linear and Multilinear Algebra, 2012
Continuing [5], this paper investigates finer points of supertropical vector spaces, including dual bases and bilinear forms, with supertropical versions of standard classical results such as the Gram-Schmidt theorem and Cauchy-Schwarz inequality, and change of base.

Linear forms with algebraic coefficients. I

Journal of Number Theory, 1971
In einer früheren Arbeit [Simultaneous approximation to algebraic numbers by rationals. Acta Math. 125, 189--201 (1970; Zbl 0205.06702)] hatte der Verf. den bekannten Satz von Roth über rationale Approximationen an eine algebraische Zahl auf simultane Approximationen übertragen, und später (Teil I) [Linear forms with algebraic coefficients. I.

Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots

Advanced Robotics Research, EarlyView.
A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.

Linear Hamiltonian behaviors and bilinear differential forms [PDF]

, 2004
We study linear Hamiltonian systems using bilinear and quadratic differential forms. Such a representation-free approach allows us to use the same concepts and techniques to deal with systems isolated from their environment and with systems subject to ...
