On Mandelshtam as a Subtext in Iosif Brodsky’s “Lullaby of Cape Cod” [PDF]

open access: yes, 2020
The article identifies the set of texts by Osip Mandelshtam which served as possible sources of allusions for Iosif Brodsky’s poem “Lullaby of Cape Cod” (also related works by Bethea, Akhapkin and Ranchin are taken into account).

Toric amplitudes and universal adjoints

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract A toric amplitude is a rational function associated with a simplicial polyhedral fan. The definition is inspired by scattering amplitudes in particle physics. We prove algebraic properties of such amplitudes and study the geometry of their zero loci. These hypersurfaces play the role of Warren's adjoint via a dual volume interpretation.

Comparison of Mandelshtam's Conditions with Convergence Conditions for Iterative Procedures in the Analysis of Complex Dynamic Systems by Means of Partial Models

open access: yesEngineering Transactions, 1992
The convergence conditions for iterative procedures in the analysis of dynamic systems with the use of partial models are compared with Mandelshtam's conditions (uncoupling of vibrations of partial models). Both basic iteration procedures are discussed.

Physicochemical Characterization of Solid Catalysts: Morphological, Structural, Textural, Reducibility, and Acid‐Base Insights

open access: yesChemCatChem, Volume 17, Issue 23, December 8, 2025.
This review provides a practical guide for the characterization of solid catalysts, emphasizing key techniques such as SEM, TEM, XRD, Raman spectroscopy, and gas physisorption. It also covers reducibility and acid‐based analyses through TPR, TPD, and FTIR.

Holomorphic field theories and higher algebra

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.
Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...
