F-biharmonic maps into general Riemannian manifolds

open access: yesOpen Mathematics, 2019
Let ψ:(M, g) → (N, h) be a map between Riemannian manifolds (M, g) and (N, h).

Group Geometrical Axioms for Magic States of Quantum Computing

open access: yesMathematics, 2019
Let H be a nontrivial subgroup of index d of a free group G and N be the normal closure of H in G. The coset organization in a subgroup H of G provides a group P of permutation gates whose common eigenstates are either stabilizer states of the Pauli ...

On new examples of Hamiltonian-minimal and minimal Lagrangian submanifolds in $C^n$ and $CP^n$

open access: yes, 2003
We propose a new method for the construction of Hamiltonian-minimal and minimal Lagrangian immersions of some manifolds in $C^n$ and in $CP^n$. By this method one can construct, in particular, immersions of such manifolds as the generalized Klein's ...

A note on generalization of Zermelo navigation problem on Riemannian manifolds with strong perturbation

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017
We generalize the Zermelo navigation on Riemannian manifolds (M; h), admitting a space dependence of a ship's speed 0 < |u(x)|h ≤ 1 in the presence of a perturbation W̃ determined by a strong (critical) velocity vector field satisfying |W̃ (x)|h = |u(x ...

Coupling of symmetric operators and the third Green identity

open access: yesBulletin of Mathematical Sciences, 2017
The principal aim of this paper is to derive an abstract form of the third Green identity associated with a proper extension T of a symmetric operator S in a Hilbert space $$\mathfrak {H}$$ H , employing the technique of quasi boundary triples for T. The

Quasi-Hamiltonian groupoids and multiplicative Manin pairs

open access: yes, 2010
We reformulate notions from the theory of quasi-Poisson g-manifolds in terms of graded Poisson geometry and graded Poisson-Lie groups and prove that quasi-Poisson g-manifolds integrate to quasi-Hamiltonian g-groupoids.

Financial Burden Associated With Hospitalisation Among Families of Childhood Brain Tumours in Australia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours

Higher-derivative couplings and torsional Riemann curvature

open access: yesJournal of High Energy Physics, 2022
Using the most general higher-derivative field redefinitions for the closed spacetime manifolds, we show that the tree-level couplings of the metric, B-field and dilaton at orders α′2 and α′3 that have been recently found by the T-duality, can be written

Two Faces of NOTCH1 in Childhood Lymphoblastic T‐Cell Neoplasia: Prognostic Divergence of Mutational and Structural Aberrations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT In pediatric patients, T‐cell lymphoblastic lymphoma (T‐LBL) survival exceeds 80%. Relapse remains associated with limited curative options. Frontline treatment is largely extrapolated from T‐cell acute lymphoblastic leukemia (T‐ALL) treatment, reflecting the ongoing debate, whether both entities represent distinct diseases or variants within ...

On formality of homogeneous Sasakian manifolds

open access: yesComplex Manifolds, 2019
In this note we show families of homogeneous Sasakian manifolds G/H which are nonformal. The non-formality condition is expressed in terms of characters of a maximal torus in G.
