Spin-spin correlators on the β/β⋆ boundaries in 2D Ising-like models: Exact analysis through theory of block Toeplitz determinants [PDF]
In this work, we investigate quantitative properties of correlation functions on the boundaries between two 2D Ising-like models with dual parameters $\beta$ and $\beta^{\star}$.

Sharp Bounds of Hermitian Toeplitz Determinants for Bounded Turning Functions
Hermitian Toeplitz determinants are used in multiple disciplines, including functional analysis, applied mathematics, physics, and engineering sciences. We calculate the sharp upper and lower bounds on the fourth-order Hermitian Toeplitz determinant for ...

Hermitian-Toeplitz determinants and some coefficient functionals for the starlike functions
In this paper, we have determined the sharp lower and upper bounds on the fourth-order Hermitian-Toeplitz determinant for starlike functions with real coefficients.

COEFFICIENT INEQUALITY FOR MULTIVALENT BOUNDED TURNING FUNCTIONS OF ORDER α
The objective of this paper is to obtain the sharp upper bound to the H_2(p + 1), second Hankel determinant for p-valent (multivalent) analytic bounded turning functions (also called functions whose derivatives have positive real parts) of order α (0 ≤ α

Hermitian-Toeplitz determinants for functions with bounded turning
: There is a rich literature on estimation of second and third Hankel determinants for normalised analytic functions in geometric function theory. It is also, therefore, natural to explore the concept of the Hermitian–Toeplitz determinants for such ...

ABSTRACT As one of the important links in energy transition and global energy interconnection, electric vehicles (EVs) are becoming increasingly major research topics in the field of energy. Partial discharge (PD) identification under repetitive impulsive voltages plays a pivotal role in evaluating the health of electric vehicle (EV) motor insulation ...

Changes in External Developmental Assets Across Adolescence in Low‐Income Urban Youth
ABSTRACT This study investigated longitudinal changes in external developmental assets (EDA)—support, empowerment, boundaries & expectations across ecological and interpersonal contexts of family, peers, school, and neighborhood—among predominantly Black, low‐income urban adolescents. A birth cohort of 367 adolescents (47% male) was assessed at ages 12,
