Intrinsic Multiperspectivity: Conceptual Forms and the Functional Architecture of the Perceptual System Rainer Mausfeld Abstract It is a characteristic feature of our mental make-up that the same percep- tual input situation can simultaneously elicit conflicting mental perspectives. This ability pervades our perceptual and cognitive domains. Striking examples are the dual character of pictures in picture perception, pretend play, or the ability to employ metaphors and allegories. I argue that traditional approaches, beyond being inadequate on principle grounds, are theoretically ill equipped to deal with these achievements. I then outline a theoretical perspective that has emerged from a theoretical convergence of perceptual psychology, ethology, linguistics, and -

How this was complished is shown with three examples of careers of famous mathematicians. 1 Introduction This symposium is dedicated to the development of mathematics in the Austro- Hungarian monarchy in the time from 1850 to 1914. At the beginning of this period, in the middle of the 19th century the level of teaching and researching mathematics was very low – with a few exceptions – due to the influence of the jesuits in former centuries, and due to the reclusive period in the first half of the 19th century. But even in this time many efforts were taken to establish a higher education. -

Gerald Teschl (University of Vienna) Dispersive Estimates Mexico, 2017 2 / 94 Linear constant coefficient ODEs We begin by looking at the autonomous linear first-order system x_(t) = Ax(t); x(0) = x0; where A is a given n by n matrix.

Munton Phil Perspectives 2
The Eye’s Mind: Perceptual Process and Epistemic Norms Jessie Munton Abstract: Philosophers have tended to formulate theories of perceptual justification independently of psychological investigation into perceptual functioning. Nevertheless, work in perceptual epistemology often conceals an implicit commitment to a normative view of what kinds of processing maximise the epistemic power of a perceptual experience, that is, its capacity to justify belief. This implicit commitment is to a set of “minimalist” norms, which treat sensory stimulation as the ultimate locus of epistemic power, and consequently set value on the purity of sensory signal and passivity of perceptual processing. These norms fit poorly with our best scientific models of perception, which draw out the ways in which it can be understood as akin to a hypothesis. Focusing on visual perception in particular, I argue that appreciating how it plays the role of a hypothesis within the visual system, whilst also constituting a form of evidence at the person level, gives us reason to reject these minimalist norms for perceptual processing.1 0. Introduction Visual experience can justify belief. Visual experience is also the result of a set of psychological processes. What is the significance of the latter set of facts for the former capacity? What role do psychological processes play in determining the epistemic value, or power, of a perceptual experience?2 According to one, influential train of thought in philosophy, the answer is, superficially at least, “none”. For the most part, epistemic norms have been formulated in isolation from psychological inquiry into perception. Philosophers have often granted perceptual experience an exceptional epistemic role: it puts us in immediate contact with the world around us, and can provide a foundational level of justification for certain basic beliefs, on which we can ground, via inference, a web of more complex beliefs. -
Notions Such As 'Truth' Or 'Correspondence to the Objective World' Play No Role in Explanatory Accounts of Perception
Mausfeld, R. (2015). Notions such as ‘truth’ or ‘correspondence to the objective world’ play no role in ex- planatory accounts of perception. Psychonomic Bulletin & Review , DOI: 10.3758/s13423-014-0763-6 Notions such as ‘truth’ or ‘correspondence to the objective world’ play no role in explanatory accounts of perception Rainer Mausfeld University of Kiel Abstract. Hoffman, Singh, and Prakash (2015) intend to show that perceptions are evolutionarily tuned to fitness rather than to truth. I argue, partly in accordance with their objective, that issues of ‘truth’ or ‘veridicality’ have no place in explanatory accounts of perception theory, and rather belong to either ordinary discourse or to philosophy. I regard, however, their general presumption that the evolutionary development of core achievements of the human perceptual system would be primarily determined by aspects of fitness and adaption as unwarranted in light of the evidence available. In our ordinary intuitions about perception, we are convinced that our perceptual apparatus by and large conveys to us a basically ‘truthful’ account of the external world. We are apparently biologi- cally endowed with a predisposition to take certain expressions generated by our perceptual capaci- ties for ‘things in the objective world’. This propensity constitutes a kind of naïve realism that is deeply built-in into our mental make-up (cf. Mausfeld, 2010a). Although naïve realism already foun- ders in the face of most elementary scientific facts, say about the properties of our sense organs, it intellectually expresses some of our deepest convictions about the mental activity of perceiving, namely, being in direct touch with a mind-independent world. -

Das Bedeutsamkeitsproblem in Der Statistik
Das Bedeutsamkeitsproblem in der Statistik Reinhard Niederée und Rainer Mausfeld Im letzten Kapitel (Niederée & Mausfeld, in diesem Band), das dem Thema Ska- lenniveau, Invarianz und „Bedeutsamkeit“ gewidmet war, haben wir uns im we- sentlichen mit der Rolle von skalenniveaubezogenen Invarianzkriterien für numeri- sche Einzelfallaussagen und gesetzesartige Aussagen befaßt. Dabei haben wir zu zei- gen versucht, daß solche Kriterien nicht als aprioristische Bedeutsamkeitspostulate mißverstanden werden dürfen, daß ihnen aber dennoch eine fruchtbare substanzwis- senschaftliche Rolle zukommen kann. In diesem Kapitel wollen wir uns mit verwand- ten Fragen im Bereich der angewandten Statistik befassen. Dabei werden wir die einschlägigen, im letzten Kapitel besprochenen Konzepte als bekannt voraussetzen (vgl. insbesondere die Abschnitte zum Skalenniveau und zu „naiven“ Invarianzkon- zepten). 1 Stevens’ Bedeutsamkeitskonzeption und die Folgen Tatsächlich hatte Stevens (z.B. 1946, 1951) primär Probleme der angewandten Stati- stik im Sinn, als er sein einflußreiches skalenniveaubezogenes Bedeutsamkeitskonzept vorschlug. Konzepte der sog. statistischen Bedeutsamkeit oder Zulässigkeit, welche in der Stevensschen Tradition stehen, finden sich bis heute in einer Vielzahl von einführenden Texten zur angewandten Statistik und zum experimentellen Design. Dabei werden für ein „gegebenes“ Skalenniveau der betrachteten Variablen nur sol- che statistischen Kennwerte (Statistiken) als „bedeutsam“ oder „zulässig“ eingestuft, welche gewisse Invarianzkriterien -

We study perturbations of the self-adjoint periodic Sturm{Liouville operator 1 d d A0 = − p0 + q0 r0 dx dx and conclude under L1-assumptions on the differences of the coefficients that the essential spectrum and absolutely continuous spectrum remain the same. If a finite first moment condition holds for the differences of the coefficients, then at most finitely many eigenvalues appear in the spectral gaps. This observation extends a seminal result by Rofe-Beketov from the 1960s. Finally, imposing a second moment condition we show that the band edges are no eigenvalues of the perturbed operator. 1. Introduction Consider a periodic Sturm{Liouville differential expression of the form 1 d d τ0 = − p0 + q0 r0 dx dx R 1 R on , where 1=p0; q0; r0 2 Lloc( ) are real-valued and !-periodic, and r0 > 0, p0 > 0 2 a. e. Let A0 be the corresponding self-adjoint operator in the weighted L -Hilbert 2 space L (R; r0) and recall that the spectrum of A0 is semibounded from below, purely absolutely continuous and consists of (finitely or infinitely many) spectral bands; cf. -

Reflectionless Operators: the Deift and Simon Conjectures
Mathematisches Forschungsinstitut Oberwolfach Report No. 49/2017 DOI: 10.4171/OWR/2017/49 Mini-Workshop: Reflectionless Operators: The Deift and Simon Conjectures Organised by David Damanik, Houston Fritz Gesztesy, Waco Peter Yuditskii, Linz 22 October – 28 October 2017 Abstract. Reflectionless operators in one dimension are particularly amen- able to inverse scattering and are intimately related to integrable systems like KdV and Toda. Recent work has indicated a strong (but not equivalent) relationship between reflectionless operators and almost periodic potentials with absolutely continuous spectrum. This makes the realm of reflectionless operators a natural place to begin addressing Deift’s conjecture on integrable flows with almost periodic initial conditions and Simon’s conjecture on gems of spectral theory establishing correspondences between certain coefficient and spectral properties. Mathematics Subject Classification (2010): 35Q53, 35B15, 47B36, 47A55. Introduction by the Organisers This mini-workshop was organized by David Damanik (Rice), Fritz Gesztesy (Bay- lor), and Peter Yuditskii (Linz). The program consisted of 15 lectures on a broad variety of problems related to the Deift and Simon conjectures, including pertur- bation theory, integrable systems, random matrix theory, character-automorphic Hardy spaces, and orthogonal polynomials. This workshop intended to provide a cutting-edge survey of new results for reflectionless operators, especially those results directed towards addressing Deift’s conjecture regarding the almost pe- riodicity of solutions to the KdV equation with almost-periodic initial data and Simon’s conjecture regarding gems of spectral theory establishing a one-to-one cor- respondence between suitable classes of coefficient data and spectral data. This 2944 Oberwolfach Report 49/2017 forum provided a great background for discussions of some of the extant open problems in the field. -
Introduction
1 Introduction: PHILOSOPHY AND SCIENCE OF VISUAL PERCEPTION AND COGNITION Consider your visual experience. In that experience, mind and world meet. The world is presented to you with its shapes, colors, and textures: a green expanse with moving blobs on it; or a whitish grey ribbon with shaped volumes of color moving at great speed. The mind responds by categorizing the objects and anticipating their behavior: here is a park with people playing volleyball, and someone is about to spike the ball; there is a busy highway as you navigate your vehicle at high speed, concerned that the car on the left is weaving a bit. Form, color, and meaning are all present at once in vision, and the objects of other senses usually are experienced as located within this visual world. The world we inhabit, the one in which we live, move, and breathe, is primarily a visual world. For this reason, vision is the most thoroughly studied of the human senses. From antiquity, the disciplines of philosophy and psychology have both given special attention to vision. Indeed, the psychology of perception is the centerpiece of psychological science. Perusing a textbook such as psychologist Stephen Palmer’s Vision Science reveals a broad range of topics, from sensory receptors and the retinal image, to the perception of color, spatial structures, motion, and events, and on to cognitive aspects of perception including object perception, conceptualization, attention, visual memory, imagery, and consciousness. These topic areas are treated experimentally and the phenomena are subject to explicit models framed within recognized theoretical traditions. Although philosophers sometimes have disparaged the notion of psychological science, in this case there can be no question of the just application of the honorific ‘‘science.’’ Sensory perception was the first topical area within psychology to which mathematics was applied, in ancient, medieval, and early modern optical 2 introduction writings (Ch. -
