Some problems in the Calculus of Variations

We present some results and open problems in the Calculus of Variations.

Inequalities of Lipschitz type for power series in Banach algebras

Let $f(z) = \sum_{n=0}^{\infty}\alpha_n z^n$ be a function defined by power series with complex coefficients and convergent on the open disk $D(0,R) \subset \mathbb{C}$, $R > 0$. For any $x, y \in \mathcal{B}$, a Banach...

A unique common fixed point for an infinity of set-valued maps

The main purpose of this paper is to establish some common fixed point theorems for single and set-valued maps in complete metric spaces, under contractive conditions by using minimal type commutativity and without conti...

Some new Ostrowski’s inequalities for functions whose nth derivatives are logarithmically convex

Some new Ostrowski’s inequalities for functions whose n-th derivative are logarithmically convex are established.

Alienation of the Jensen, Cauchy and d’Alembert equations

Let $(S,+)$ be a commutative semigroup, $\sigma : S \to S$ be an endomorphism with $\sigma^2 = id$ and let $K$ be a field of characteristic different from 2. Inspired by the problem of strong alienation of the Jensen eq...
