$(varphi_1, varphi_2)$-variational principle

In this paper we prove that if $X $ is a Banach space, then for every lower semi-continuous bounded below function $f, $ there exists a $left(varphi_1, varphi_2right)$-convex function $g, $ with arbitrarily small norm,  such that $f + g $ attains its strong minimum on $X. $ This result extends some of the  well-known varitional principles as that of Ekeland [On the variational principle,  J. Ma...

A Variational Principle in Discrete Space-Time – Existence of Minimizers

We formulate a variational principle for a collection of projectors in an indefinite inner product space. The existence of minimizers is proved in various situations. In a recent book it was proposed to formulate physics with a new variational principle in space-time [2]. In the present paper we construct minimizers of this variational principle. In order to make the presentation self-contained...

The Principle of the Fermionic Projector: A New Variational Principle in Space-Time

In this short review, we introduce the mathematical framework of the principle of the fermionic projector and set up a variational principle in discrete space-time. The connection to the continuum theory is outlined. Recent results and open problems are discussed. The principle of the fermionic projector [1] provides a new model of space-time together with the mathematical framework for the for...

Variational principle and phase space measure in non-canonical coordinates

Theoretical formalisms very often use non-canonical equations of motion. For example, the equations for Eulerian variables, that describe ideal continuous media, are in general non-canonical [1]. Non-canonical phase space flows can be derived from Hamiltonian dynamics by means of non-canonical transformations of phase space coordinates (i.e. transformations with Jacobian not equal to one) while...
