The minimax theorem as Hahn-Banach theorem consequence [PDF]
, 2019 The separation concept is essential in convex programming. In particular, the convex sets separation. In this work the Hahn-Banach theorem is presented, with great generality, together with an important separation theorem, its consequence.

Plank theorems and their applications: A survey
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract Plank problems concern the covering of convex bodies by planks in Euclidean space and are related to famous open problems in convex geometry. In this survey, we introduce plank problems and present surprising applications of plank theorems in various areas of mathematics.

O Teorema de Hahn Banach [PDF]
, 2022 This work consists of the study of one of the most important theorems of Functional Analysis, the Hahn-Banach Theorem. Here, in addition to approaching the theorem in its classic versions found in the Introduction to Functional Analysis books, the ...

Der Satz von Hahn-Banach per Disjunktionselimination [PDF]
, 2019 The Hahn-Banach extension theorem is at once main pillar of functional analysis and — due to its notorious nature as consequence of the axiom of choice — prime example of a pure existential statement. By way of a general syntactic conservation result for

Ramified Asymptotic Expansions for Some Linear Initial Value Problem With Mahler Transforms
Abstract and Applied Analysis, Volume 2026, Issue 1, 2026.We focus on a linear partial differential initial value problem in complex time t and complex space combined with time acting Mahler transforms. Bounded holomorphic solutions on bounded sectors edged at the origin in time and on horizontal strips in space are constructed by means of infinite sums of Fourier–Laplace transforms.

Uniformly Continuous Functionals and Operators Commuting with Lebesgue–Fourier Algebras
Journal of Function Spaces, Volume 2026, Issue 1, 2026.Let G be a locally compact group. This paper investigates the space of uniformly continuous functionals associated with the Lebesgue–Fourier algebra on G. Our aim is to describe the dual of this space in terms of bounded operators on the dual of the Lebesgue–Fourier algebra that commute with the natural module action, and to determine exactly when this

On ℬ‐Analog of the Sumudu Transform Associated With the General Quantum ℬ‐Difference Operator
Journal of Mathematics, Volume 2026, Issue 1, 2026.We present here a B‐analog of the Sumudu transform defined via a general quantum B‐difference operator which generalizes classical difference operators in the context of quantum calculus, is employed to study the proposed problem. We explore the core characteristics of the B‐Sumudu transform and illustrate its applications in solving B‐initial value ...

On Hermite–Hadamard Inequalities for Generalized Quantum Interval Calculus
Journal of Mathematics, Volume 2026, Issue 1, 2026.In this paper, we develop the theory of β,gH‐calculus for interval‐valued functions by combining the β‐functions with the generalized Hukuhara difference. Within this framework, we establish various properties related to β,gH‐differentiation and β,gH‐integration.

Analytical method for solving linear abstract differential equations of order n
Partial Differential Equations in Applied MathematicsIn this paper, the concept of point-wise independent set of closed operators is introduced. The new concept together with the use of Hahn–Banach Theorem enable us to reduce an inhomogeneous linear abstract differential equation of order n namely, Anu(n ...
