Hardy's Inequality for Dirichlet Forms
Journal of Mathematical Analysis and Applications, 2000 The aim of the paper is to give necessary and sufficient conditions for the validity of an abstract form of Hardy's \(L^2\) inequality in which the Dirichlet integral is replaced by the Dirichlet form of a general symmetric Markov process. The case of equality in a given inequality is described. The general result is illustrated with examples.

Business Strategy and the Environment, EarlyView.ABSTRACT Sustainability reports (SRs) are widely criticized for vague disclosures and selective emphasis on positive outcomes, yet systematic research on two core SR challenges remains limited: materiality (whether disclosed content is relevant) and balance (whether both achievements and challenges are reported).

Homology groups in CR-warped products of complex space forms
HeliyonIn the present paper, by using the result of Lawson-Simons [15], we adopt a different technique to show that there are no stable integral q-currents and a non-trivial homology group in a compact oriented CR-warped product submanifold Nn in a complex ...

, 2021 In den letzten fünfzig Jahren haben eine Vielzahl von Mathematikern, allen voran Brezis, Pazy und Crandall, eine Theorie der nichtlinearen Halbgruppen entwickelt. Die Ergebnisse dieser Theorie ähneln denen des linearen Gegenstücks stark. Insbesondere zeigten sie, dass jedes konvexe und unterhalbstetige Funktional auf einem Hilbertraum eine ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study explores how circular economy (CE) principles are incorporated in construction‐related policy roadmaps worldwide, addressing the growing need for effective resource strategies in a highly material‐intensive sector. National strategic CE documents from 57 countries were analyzed using natural language processing techniques, and then ...

Business Strategy and the Environment, EarlyView.ABSTRACT Widespread digital adoption has challenged our understanding of how these tools reshape collaboration, trust and sustainability outcomes across different institutional and network contexts. As networks now pursue resilience and sustainable development in parallel, we map emerging research directions and identify how collaboration and ...

Finite difference and finite element methods for partial differential equations on fractals
Revista Integración, 2022 In this paper, we present numerical procedures to compute solutions of partial differential equations posed on fractals. In particular, we consider the strong form of the equation using standard graph Laplacian matrices and also weak forms of the ...

Business Strategy and the Environment, EarlyView.ABSTRACT Corporate environmental communication has become an essential aspect of modern business practices, as stakeholders increasingly demand transparency and accountability regarding sustainability efforts. Within this context, we examine whether firms use environmental communication on X/Twitter to offset weaker relative environmental performance ...

Dirichlet Forms and Degenerate Elliptic Operators [PDF]
, 2006 It is shown that the theory of real symmetric second-order elliptic operators in divergence form on $\Ri^d$ can be formulated in terms of a regular strongly local Dirichlet form irregardless of the order of degeneracy. The behaviour of the corresponding evolution semigroup $S_t$ can be described in terms of a function $(A,B) \mapsto d(A ;B)\in[0,\infty]
