Boundedness on inhomogeneous Lipschitz spaces of fractional integrals, singular integrals and hypersingular integrals associated to non-doubling measures

In the context of a finite measure metric space whose measure satisfies a growth condition, we prove "T1" type necessary and sufficient conditions for the boundedness of fractional integrals, singular integrals, and hypersingular integrals on inhomogeneous Lipschitz spaces. We also indicate how the results can be extended to the case of infinite measure. Finally we show applications to Real and Complex Analysis.Comment: 16 page

Catalan Traffic and Integrals on the Grassmannians of Lines

We prove that certain numbers occurring in a problem of paths enumeration, studied by Niederhausen (Catlan Traffic at the Beach, The Electronic Journal of Combinatorics, 9, (2002), 1--17), are top intersection numbers in the cohomology ring of the grassmannians of the lines in the complex projective (n+1)-space.Comment: Excerpt from my Ph.D. Thesis; to appear on "Discrete Mathematics

Collectivity and Criticism: (Fragments of) Conversations on Post-dance

Post-dance first unfolded as a conference in MDT in Stockholm, 14-16 October, 2015, created by Danjel Andersson, Andre Lepecki and Gabriel Smeds, and was followed by a multi-authored publication co-edited by Andersson, Mette Edvardsen and Mårten Spångberg (March 2017) that sought to delineate post-dance as a mode of thinking about an expanded contemporary dance and choreographic practice. This experiment in collective criticism thinks through and around post-dance as a critical moment in contemporary dance practice. Authored by Writingshop, a long-term collaborative project between four European critics examining the processes, modes and politics of contemporary, collective critical practice, it intersperses multi-authored notes from and on post-dance with a timeline. This timeline is an edited transcript of the conversation that gave rise to the notes, taking place in a side-chat, on a live Google document. At the same time, whilst this has been a process of selection, there has been little editorial intervention into the chat, in order to preserve its chronology and dynamics, and acknowledge the challenges of us arriving in this document together, from four different places, with different forms of access and points of entry into language

Disturbances, robustness and adaptation in forest commons: comparative insights from two cases in the Southeastern Alps

Exposure to disturbances of different nature and scale can represent a threat for the survival of rural communities but also a stimulus to adjustment. Disturbance, robustness and adaptation are here examined through the lens of Forest Commons, as a typical institution, developed by communities in the southeastern Alps since several centuries. The paper relies on Commons' theory and further developments and carries out a historically-embedded analysis of disturbances, robustness and adaptation in Forest Commons of Slovenia and Veneto (Italy). Data have been drawn from multiple sources, following an approach based on an area scale and later on case-studies. The analysis focuses on evidence of Forest Commons\ub4 reactions to disturbances induced by political changes and State actions. Ostrom's design principles are used to test robustness of eight selected cases and identification of their adaptation patterns. The paper concludes by confirming Forest Commons as robust and adaptive socio-ecological systems and thus useful in Community Forestry conceptualisation. However, thanks to its cross-border analysis, it also points out future research needs for their better understanding
