The diffi culty that each of us faces in seeking to comprehend death is neatly expressed by Wittgenstein in the epigraph at the head of this chapter. A related insight of the sculptor Damien Hirst led him to create the work entitled ‘The physical impossibility of death in the mind of someone living’, which was fi rst shown at the Serpentine Gallery in London in 1992 (Gallagher 2012 ; frontispie...

to read the text of Michel foucault’s late seminars on the topic of parrhesia from the perspective of the work of nearly a decade earlier on the topics of disciplinary power and biopower, one is struck by the seemingly irreconcilable positions he adopts in these two periods on the topic of ‘truth’ [la vérité]. his 1983 Berkeley seminar places considerable emphasis on the courage of the parrhesi...

The paper reviews the image of Vasyl Stus in Roman Brovko’s feature film “The Proscribed” (“Zaboronenyi”, 2019). researcher aims to find out how director embodies psychological structure writer’s personality for a wide audience. To do this, author uses interviews with director, leading actor, and contemporaries
 Stus, analyzing from perspective its form, content, meaning.

The abscissa mapping on the affine variety Mn of monic polynomials of degree n is the mapping that takes a monic polynomial to the maximum of the real parts of its roots. This mapping plays a central role in the stability theory of matrices and dynamical systems. It is well known that the abscissa mapping is continuous on Mn, but not Lipschitz continuous. Furthermore, its natural extension to t...

disappointed by the weak annotations, insufficient subject indexing, and limited chronological span, as well as the absence of writings in languages other than Eng-lish. As a result, most researchers will continue to rely on Meadows as their primary jazz bibliography, and only libraries with very ambitious collecting missions in the area of jazz should feel it necessary to purchase Jazz Books i...

In 1788, the Scottish physician John Ferriar published an ‘altered’ stage version of Oroonoko that ‘adapted’ the play to the ‘circumstances of the present times’.[1] In his preface to the play, Ferriar explains that ‘when the attempt to abolish the African Slave Trade commenced in Manchester, some active friends of the cause imagined, that by assembling a few of the principal topics, in a drama...

We study the Hausdorff dimension of the set of non-Lipschitz points S of the minimum time function T under controllability conditions which imply the continuity of T . We consider first the case of normal linear control systems with constant coefficients in RN . We characterize S as the set of points which can be reached from the origin by an optimal trajectory (of the reversed dynamics) with v...

We show that for any given norm ball or proper cone, weak membership in its dual ball or dual cone is polynomial-time reducible to weak membership in the given ball or cone. A consequence is that the weak membership or membership problem for a ball or cone is NP-hard if and only if the corresponding problem for the dual ball or cone is NP-hard. In a similar vein, we show that computation of the...

Many iterative methods for solving optimization or feasibility problems have been invented, and often convergence of the iterates to some solution is proven. Under favourable conditions, one might have additional bounds on the distance of the iterate to the solution leading thus to worst case estimates, i.e., how fast the algorithm must converge. Exact convergence estimates are typically hard t...

Following the theory of idempotent measures of Maslov, a formalism analogous to probability calculus is obtained for optimization by replacing the classical structure of real numbers (R;+; ) by the idempotent semield obtained by endowing the set R [ f+1g with the \min" and \+" operations. To the probability of an event corresponds the cost of a set of decisions. To random variables correspond d...
