Calculus of conformal fields on a compact Riemann surface

, 2017
We present analytical implementation of conformal field theory on a compact Riemann surface. We consider statistical fields constructed from background charge modifications of the Gaussian free field and derive Ward identities which represent the Lie derivative operators in terms of the Virasoro fields and the puncture operators associated with the ...

Opial inequalities for a conformable ∆-fractional calculus on time scales

Mathematica Moravica
In this paper, an Opial-type inequality is introduced on time scale for a conformal ∆-fractional differentiable function of order a, a ∈ (0, 1]. In the case where the certain weight functions are included, one generalization of the Opial inequality is proved using conformal ∆-fractional calculus on time scales.

Conformal Thermoreversible Gelatin‐Based Gel for High‐Fidelity Electrophysiological Recording and Acute Peripheral Nerve Interfacing

Advanced Materials, EarlyView.
A thermoreversible gelatin‐based gel forms a soft, conformal bioelectronic interface on complex biological surfaces. The flowable precursor penetrates hair‐dense regions, solidifies in situ, and maintains low impedance through adaptive contact and hydration retention.

Conformal geometry, contact geometry, and the calculus of variations

Duke Mathematical Journal, 2000
Let \((N,g_0)\) be a compact Riemannian manifold of dimension \(n\geq 3\). In this paper, the author considers the curvature equations \[ \sigma_k\left( \text{Ric}_g-{R_g\over 2(n-1)} \cdot g\right)= \text{constant} \tag{1} \] for metrics \(g\) in the conformal class of \(g_0\), where \(\text{Ric}_g\) and \(R_g\) are the Ricci tensor and the scalar ...

Fast Hydrogel Micro‐Actuators Driven by Electric Fields

Advanced Materials, EarlyView.
We report the fabrication of chemically programmable electroactuating microstructures through the first integration of two‐photon polymerization with electrically actuated gelatin methacrylate‐based hydrogels. By tailoring the charge of the polymer network, we demonstrate programmable polarity‐dependent bending, enabling microstructures that ...
