On CR-Lightlike Product of an Indefinite Kaehler Manifold
International Journal of Mathematics and Mathematical Sciences, 2011 We have studied mixed foliate CR-lightlike submanifolds and CR-lightlike product of an indefinite Kaehler manifold and also obtained relationship between them.

Indefinite Eigenvalue Problems for p-Laplacian Operators with Potential Terms on Networks
Abstract and Applied Analysis, 2014 We address some forward and inverse problems involving indefinite eigenvalues for discrete p-Laplacian operators with potential terms. These indefinite eigenvalues are the discrete analogues of p-Laplacians on Riemannian manifolds with potential terms ...

A purification postulate for quantum mechanics with indefinite causal order [PDF]
Quantum, 2016 To study which are the most general causal structures which are compatible with local quantum mechanics, Oreshkov et al. introduced the notion of a process: a resource shared between some parties that allows for quantum communication between them without

Complex oscillations of non-definite Sturm-Liouville problems
Electronic Journal of Differential Equations, 2016 We expand upon the basic oscillation theory for general boundary problems of the form $$-y''+q(t)y=\lambda r(t)y, \quad t \in I = [a,b] $$ where q and r are real-valued piecewise continuous functions and y is required to satisfy a pair of ...

Indefinite Ruhe’s Variant of the Block Lanczos Method for Solving the Systems of Linear Equations
Advances in Mathematical Physics, 2020 In this paper, we equip Cn with an indefinite scalar product with a specific Hermitian matrix, and our aim is to develop some block Krylov methods to indefinite mode.

Journal of Function Spaces, 2018 In this paper, a class of indefinite hypersurfaces and a class of indefinite surfaces generated by timelike curves located in nullcone in 4-dimensional semi-Euclidean space with index 2 are discussed. Using the unfolding theory in singularity theory, the

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.

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 ...

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.
