The categorical DT/PT correspondence and quasi-BPS categories for local surfaces

Posted by klaurent Tokyo

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: We construct semiorthogonal decompositions of Donaldson-Thomas (DT) categories for reduced curve classes on local surfaces into products of quasi-BPS categories and Pandharipande-Thomas (PT) categories, giving a categorical analogue of the numerical DT/PT correspondence for Calabi-Yau 3-folds. The main ingredient […]

The local categorical DT/PT correspondence

Posted by klaurent Tokyo

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: In this paper, we prove the categorical wall-crossing formula for certain quivers containing the three loop quiver, which we call DT/PT quivers. These quivers appear as Ext-quivers for the wall-crossing of DT/PT moduli spaces on Calabi-Yau 3-folds. The resulting […]

Coherent Sheaves, Chern Classes, and Superconnections on Compact Complex-Analytic Manifolds

Posted by klaurent Tokyo

Kavli Affiliate: Alexey Bondal | First 5 Authors: Alexey Bondal, Alexei Rosly, , , | Summary: We construct a twist-closed enhancement of the category ${mathcal D}^b_{rm coh}(X)$, the bounded derived category of complexes of ${mathcal O}_X$-modules with coherent cohomology, by means of the DG-category of $barpartial$-superconnections. Then we apply the techniques of $barpartial$-superconnections to define […]

Subcellular niche segregation of co-obligate symbionts in whiteflies

Posted by klaurent UCSD / Salk

Kavli Affiliate: Ying Meng | Authors: Akiko FUJIWARA, Xian-Ying Meng, Yoichi Kamagata and Tsutomu TSUCHIDA | Summary: Abstract Many insects contain endosymbiotic bacteria within their bodies. In multiple endosymbiotic systems comprising two or more symbionts, each of the symbionts is generally localized in a different host cell or tissue. Bemisia tabaci （Sweet potato whitefly）possesses a […]

Quadratic computations maintain neural specificity to natural stimuli across stages of visual processing

Posted by klaurent UCSD / Salk

Kavli Affiliate: Tatyana Sharpee | Authors: Ryan J. Rowekamp and Tatyana Sharpee | Summary: Abstract Despite recent successes in machine vision, artificial recognition systems continue to be less robust than biological systems. The brittleness of artificial recognition system has been attributed to the linearity of the core operation that matches inputs to target patterns at […]

Radiation from Global Topological Strings using Adaptive Mesh Refinement: Massive Modes

Posted by klaurent Cambridge

Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Amelia Drew, E. P. S. Shellard, , , | Summary: We implement adaptive mesh refinement (AMR) simulations of global topological strings using the public code, GRChombo. We perform a quantitative investigation of massive radiation from single sinusoidally displaced string configurations, studying a range of string […]

Soliton generation in AlGaAs microresonators at room temperature

Posted by klaurent Caltech

Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Lue Wu, Weiqiang Xie, Chao Xiang, Lin Chang, Yan Yu | Summary: Chip-integrated optical frequency combs are attractive optical sources in comb applications requiring high-repetition-rate, low power consumption, or compact size. Spontaneous soliton formation via Kerr parametric oscillation is a promising generation principle in these frequency […]
