The advantage of the proposed approach is that it operates in terms of finite-dimensional spaces and avoids working with quotient spaces such as local functionals or functionals modulo on-shell trivial ones. The structure that is being deformed is that of a presymplectic gauge PDE, which consists of a graded presymplectic structure and a compatible odd vector field. These are known to encode the Batalin–Vilkovisky (BV) formulation of a local gauge theory in terms of the finite dimensional supergeometrical object. Although in its present version the method is limited to interactions that do not deform the presymplectic structure and relies on some natural assumptions, it gives a remarkably simple way to analyse consistent interactions. The approach can be considered as the BV-AKSZ extension of the frame-like approach to consistent interactions. We also describe the underlying homological deformation theory, which turns out to be slightly unusual compared to the standard deformations of differential graded Lie algebras. As an illustration, the Chern-Simons and YM theories are rederived starting from their linearized versions.</p></div>","PeriodicalId":463,"journal":{"name":"Annales Henri Poincaré","volume":"27 9","pages":"3329 - 3350"},"PeriodicalIF":1.4,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148974819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In many applications only part of the information contained in the filter’s state is actually needed to reconstruct the target observable quantities; thus, filters of smaller dimensions could be in principle implemented to perform the same task. In this work, we propose a systematic method to find, when possible, reduced-order quantum filters that are capable of exactly reproducing the evolution of expectation values of interest. In contrast with existing reduction techniques, the reduced model we obtain is exact and in the form of a Belavkin filtering equation, ensuring physical interpretability. This is attained by leveraging tools from the theory of both minimal realization and non-commutative conditional expectations. The proposed procedure is tested on prototypical examples, laying the groundwork for applications in quantum trajectory simulation and quantum feedback control.</p></div>","PeriodicalId":463,"journal":{"name":"Annales Henri Poincaré","volume":"27 10","pages":"3731 - 3783"},"PeriodicalIF":1.4,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00023-025-01622-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149162985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First we prove the Kato–Yajima-type uniform resolvent estimates for the repulsive Schrödinger operator with logarithmic decaying weight functions. This is new even when without perturbations. Moreover, our class of perturbations includes logarithmic decaying potentials, which is also new. The proof depends on the microlocal analysis and the Mourre theory. Then we use the Kato–Yajima estimates to prove the orthonormal Strichartz estimates. In the proof, we also use an abstract Ginibre–Velo or Keel–Tao-type theorem for the orthonormal Strichartz estimates, which means that the dispersive estimates yield the orthonormal Strichartz estimates for strongly continuous unitary groups. This abstract theorem is a partial extension of the recent results by Nguyen (J Funct Anal 286(1):110196, 2024) and also applies to many other Schrödinger propagators which are difficult to treat by the smooth perturbation theory, for example, local-in-time estimates for the Schrödinger operator with unbounded electromagnetic potentials, for the (<i>k</i>, <i>a</i>)-generalized Laguerre operators and global-in-time estimates for the Schrödinger operator with scaling critical magnetic potentials including the Aharonov–Bohm potentials. Finally, we also discuss mapping properties of resolvents of the repulsive Schrödinger operator on the Schwartz class. Since the principle symbol of our Hamiltonian does not belong to good symbol classes, resolvents do not preserve the Schwartz class. However, we prove that functions in the range of resolvents are Schwartz functions microlocally outside the radial sink. These results are different from related works Taira (Commun Math Phys 388(1):625–655, 2021) and Kameoka (J Spectr Theory 11(2):677–708, 2021).</p></div>","PeriodicalId":463,"journal":{"name":"Annales Henri Poincaré","volume":"27 10","pages":"3673 - 3729"},"PeriodicalIF":1.4,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00023-025-01616-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149162986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
