Boundedness of the Hilbert transform on Besov spaces

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2020
The Hilbert transform along curves is of a great importance in harmonic analysis. It is known that its boundedness on $L^p(\mathbb{R}^n)$ has been extensively studied by various authors in different contexts and the authors gave positive results for some

K_l3 form factors at order p^6 in chiral perturbation theory [PDF]

open access: yes, 2001
This paper describes the calculation of the semileptonic K_l3 decay form factor at order p^6 of chiral perturbation theory which is the next-to-leading order correction to the well-known p^4 result achieved by Gasser and Leutwyler.

Signed Selmer Groups over p-adic Lie Extensions [PDF]

open access: yes, 2011
Let $E$ be an elliptic curve over $\mathbb{Q}$ with good supersingular reduction at a prime $p\geq 3$ and $a_p=0$. We generalise the definition of Kobayashi's plus/minus Selmer groups over $\mathbb{Q}(\mu_{p^\infty})$ to $p$-adic Lie extensions $K_\infty$

Three positive solutions for a nonlinear partial discrete Dirichlet problem with ( p , q ) $(p,q)$ -Laplacian operator

open access: yesBoundary Value Problems, 2022
In this paper, we prove the existence of three solutions to a partial difference equation with ( p , q ) $(p,q)$ -Laplacian operator by using critical point theory. Furthermore, based on the strong maximum principle, we prove that the three solutions are

Duality Cascade and Oblique Phases in Non-Commutative Open String Theory [PDF]

open access: yes, 2001
We investigate the complete phase diagram of the decoupled world-sheet theory of (P,Q) strings. These theories include 1+1 dimensional super Yang-Mills theory and non-commutative open string theory.

Composite Operators and Topological Contributions in Gauge Theory [PDF]

open access: yes, 2001
In $D$-dimensional gauge theory with a kinetic term based on the p-form tensor gauge field, we introduce a gauge invariant operator associated with the composite formed from a electric $(p-1)$-brane and a magnetic $(q-1)$-brane in $D=p+q+1$ spacetime ...

Chern-Simons Theory on L(p,q) Lens Spaces and Localization [PDF]

open access: yesJournal of the Korean Physical Society, 2019
Using localization technique, we calculate the partition function and the expectation value of Wilson loop operator in Chern-Simons theory on general lens spaces L(p,q)(including S2XS1). Our results are consistent with known results.
