INVARIANT SUBSPACES IN UNBOUNDED DOMAINS
Проблемы анализа, 2021 We study subspaces of functions analytic in an unbounded convex domain of the complex plane and invariant with respect to the differentiation operator.

The Invariant Subspace Problem for Separable Hilbert Spaces
AxiomsIn this paper, we prove that every bounded linear operator on a separable Hilbert space has a non-trivial invariant subspace. This answers the well-known invariant subspace problem.

Subspace discovery for video anomaly detection [PDF]
, 2010 PhDIn automated video surveillance anomaly detection is a challenging task. We address this task as a novelty detection problem where pattern description is limited and labelling information is available only for a small sample of normal instances.

Subspace-Invariant AC$^0$ Formulas [PDF]
Logical Methods in Computer Science, 2019 We consider the action of a linear subspace $U$ of $\{0,1\}^n$ on the set of AC$^0$ formulas with inputs labeled by literals in the set $\{X_1,\overline X_1,\dots,X_n,\overline X_n\}$, where an element $u \in U$ acts on formulas by transposing the $i$th ...

Optimizing option pricing: Exact and approximate solutions for the time-fractional Ivancevic model
Alexandria Engineering Journal, 2023 This research investigates the time fractional Ivancevic option pricing model and presents two distinct solution methods: the invariant subspace method for obtaining exact solutions and the residual power series method for generating approximate ...

Hidden symmetries and large N factorisation for permutation invariant matrix observables
Journal of High Energy Physics, 2022 Permutation invariant polynomial functions of matrices have previously been studied as the observables in matrix models invariant under S N , the symmetric group of all permutations of N objects.

On Invariant Graph Subspaces [PDF]
Integral Equations and Operator Theory, 2016 In this paper we discuss the problem of decomposition for unbounded $2\times 2$ operator matrices by a pair of complementary invariant graph subspaces. Under mild additional assumptions, we show that such a pair of subspaces decomposes the operator matrix if and only if its domain is invariant for the angular operators associated with the graphs.
