Let X be a compact connected Riemann surface of genus g ≥ 1 equipped with nonzero holomorphic 1-form. MX(r) denote the moduli space semistable Higgs bundles on rank r and degree r(g − 1) + 1; it is complex symplectic manifold. Using translation structure open subset where 1-form does not vanish, we construct natural deformation quantization certain nonempty Zariski MX(r).

Low-rank and sparsity-matrix decomposition (LRaSMD) has received considerable interests lately. One of effective methods for LRaSMD is called go (GoDec), which finds low-rank sparse matrices iteratively subject to the predetermined matrix order $m$ sparsity cardinality $k$ . This article presents an orthogonal subspace-projection (OSP) version GoDec be OSP-GoDec, implements in iterative process...

In this paper, we study estimates for quadratic forms of the type xTA?mx, m?N, symmetric matrices. We derive a general approach estimating form and present some upper bounds corresponding absolute error. Specifically, consider three different approaches xTA?mx. The first is based on projection method, second minimization procedure, last heuristic. Numerical examples showing effectiveness are pr...

In this study, surface chemistry and flotation properties of the gold-bearing galena pyrite minerals Menderes region, Izmir, Turkey were investigated with use xanthate-thiocarbamate-monothiophosphate collectors. context, micro-flotation experiments, zeta potential, bubble-particle attachment time measurements conducted in presence Thiophosphate (Aero S-8045), Xanthate (SIBX), Thiocarbamate floa...

Electrical energy storage devices are crucial for and distribution purposes. MXene (MX), a 2D material, conductive organic polymers, such as polypyrrole (PPy), have been widely used electrode material in electronic devices. This work calculated the elastic modulus electrical conductivity of MX/PPy nanocomposite using finite element model. Response Surface Methodology (RSM) was to optimize respo...
