Canonical Kummerian Kernels in 1-Smooth Pro- Poincaré Duality Groups of Dimension Three
Marina Palaisti
Let be a finitely generated 1-smooth oriented pro- group with torsion-free orientation, and suppose that is a Poincaré duality pro- group of dimension three. The…
Modelling Robust Lending Decisions under Climate Scenario Ambiguity: A Minimax-Regret Framework with NGFS Short-Term Scenarios
Marina Palaisti
This paper develops a public-data framework for evaluating incremental bank lending when plausible climate scenarios imply different sector credit outcomes but defensible scenario…
Climate aware lending allocation under NGFS scenarios - A Monte Carlo approach
Marina Palaisti
This paper develops a framework to assess loan portfolio budget in credit portfolios exposed to climate risk over a 3-5 year horizon. Using short-term scenarios from the NGFS, the…
Detecting Cohomological Dimension Three in Free-by-Demuškin Pro- Groups
Marina Palaisti
Let \[1\longrightarrow N\longrightarrow G\longrightarrow D\longrightarrow1\] be exact, with free pro- of arbitrary rank and Demuškin. Writing , we prove \…
Higher Massey Products in Demuškin Variations: Support Blocks, One-Relator Reduction, and a Five-Fold Vanishing Case
Marina Palaisti
Blumer and Quadrelli introduced a family of two-relator pro- groups obtained from a Demuškin group by imposing the commutativity of two generators which are not…
From Common-Slot Chains to Heisenberg Central Products over Global Fields
Marina Palaisti
Let be a global field and let be an odd prime with . Assuming first that , we record in a uniform global-field form the length-four…
Coordinate-Deletion Bundles from Composition Algebras: Hopf Defects, -Classes, and Real Projective Space
Marina Palaisti
Let \(D\in\{\C,\Hh,\Oct\}\) be a real composition division algebra of dimension \(d\in\{2,4,8\}\). We construct an explicit rank-\(d\) real vector bundle $ E_D\longrightarrow\RP^d$…
Ramification Subgroups of Knot Groups and their Profinite and Cohomological Structure
Marina Palaisti, Federico W. Pasini
We formalize a ramification theory for finite covers of knot exteriors. Given a knot group and a finite-index subgroup , we define meridional inertia subgroups $U\c…
Local Nonconvexity Indices for \(C^{1,1}\) Functions via Generalized Hessians
Marina Palaisti
Davydov, Moldavskaya, and Zitikis introduced local indices for quantifying the lack of convexity of a \(C^2\) function by measuring the nuclear-norm distance of its Hessian from th…
Marginal Persistence and Dynamic Copula Dependence in Sovereign Rating Migration Counts: A Discrete Interval-Likelihood MAGMAR Analysis
Marina Palaisti
This paper develops an observed-data likelihood for applying moving-aggregate modified autoregressive (MAGMAR) copula time-series models to discrete sovereign rating-migration coun…
Asymptotic Universal Koszulity in Galois Cohomology
Marina Palaisti
We introduce the notion of asymptotic universal Koszulity for graded-commutative algebras generated in degree~, capturing the idea that an infinite-dimensional algebra can be ap…
Low-Rank and Sparse Drift Estimation for High-Dimensional Lévy-Driven Ornstein--Uhlenbeck Processes
Marina Palaisti
We study drift estimation for discretely observed high-dimensional Lévy-driven Ornstein--Uhlenbeck processes when the drift admits a low-rank-plus-sparse approximation. A localized…
Fibre-Product Stability, Kummer Gluing, and Composita for Universal Koszulity
Marina Palaisti
We study universal Koszulity under algebraic gluing and field composita. For quadratic fibre products, orthogonally split pullbacks reduce to direct sums, while Stanley--Reisner pu…
Enhanced Koszul properties in Galois cohomology
Jan Minac, Marina Palaisti, Federico W. Pasini +1
We prove that Galois cohomology satisfies several surprisingly strong versions of Koszul properties, under a well known conjecture, in the finitely generated case. In fact, these v…
