A note on indefinite integrals [PDF]
Proceedings of the American Mathematical Society, 1965 In this note all functions are measurable, complex valued and periodic on the real line; all distributions are tempered and periodic on the real line. Periodic means periodic of period 27r. If f is a function iJf(X)jjp,dp(z) is the LP norm of f, taken with respect to the measure du on [0, 27r]; IIfllp is the LP norm taken with respect to ordinary ...

Indefinite Kernel Fisher discriminant
, 2008 Indefinite kernels arise in practice, e.g. from problem-specific kernel construction. Therefore, it is necessary to understand the behavior and suitability of classifiers in the corresponding indefinite inner product spaces.

Theory of Supercritical Coupling and Generalized Bound States in the Continuum
Laser &Photonics Reviews, EarlyView.We develop a general theory of supercritical coupling and generalized bound states in the continuum (gBICs), revealing how interference between radiative and absorptive channels enables quality factors beyond conventional material‐loss limits. The framework unifies non‐Hermitian mode coupling, causality‐driven reactive interactions, and interference ...

Open Mathematics, 2017 In calculus, an indefinite integral of a function f is a differentiable function F whose derivative is equal to f. The main goal of the paper is to generalize this notion of the indefinite integral from the ring of real functions to any ring.

Young children's use of the definite and in definite articles in referring expressions [PDF]
, 1986 It is argued that the theoretical framework used in earlier studies of children's use of the articles is inadequate, failing in some important ways to capture even normal adult usage.

Kuga–Satake Construction on Families of K3 Surfaces of Picard Rank 14
Mathematische Nachrichten, EarlyView.ABSTRACT The isometry between the type IV6 and the type II4 hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank 14 and of polarized abelian 8‐folds with totally definite quaternion multiplication. We show how this isometry induces a geometrically meaningful map between such moduli spaces

Totally Contact Umbilical Lightlike Hypersurfaces of Indefinite -Manifolds
Journal of Mathematics, 2013 We study totally contact umbilical lightlike hypersurfaces of indefinite -manifolds and prove the nonexistence of totally contact umbilical lightlike hypersurface in indefinite -space form.

Non-real eigenvalues of nonlocal indefinite Sturm–Liouville problems
Boundary Value Problems, 2019 The present paper deals with non-real eigenvalues of regular nonlocal indefinite Sturm–Liouville problems. The existence of non-real eigenvalues of indefinite Sturm–Liouville differential equation with nonlocal potential K ( x , t ) $K(x,t)$ associated ...
