Harmonic and Complex Analysis and Its Applications
Trends in Mathematics Alexander Vasil’ev Editor Harmonic and Complex Analysis and its Applications Trends in Mathematics Trends in Mathematics is a series devoted to the publication of volumes arising from conferences and lecture series focusing on a particular topic from any area of mathematics. Its aim is to make current developments available to the community as rapidly as possible without compromise to quality and to archive these for reference. Proposals for volumes can be submitted using the Online Book Project Submission Form at our website www.birkhauser-science.com. Material submitted for publication must be screened and prepared as follows: All contributions should undergo a reviewing process similar to that carried out by journals and be checked for correct use of language which, as a rule, is English. Articles without proofs, or which do not contain any significantly new results, should be rejected. High quality survey papers, however, are welcome. We expect the organizers to deliver manuscripts in a form that is essentially ready for direct reproduction. Any version of TEX is acceptable, but the entire collection of files must be in one particular dialect of TEX and unified according to simple instructions available from Birkhäuser. Furthermore, in order to guarantee the timely appearance of the proceedings it is essential that the final version of the entire material be submitted no later than one year after the conference.

A Historical Overview
From the Hele-Shaw Experiment to Integrable Systems: A Historical Overview Alexander Vasil’ev to Bj¨orn Gustafsson on the occasion of his 60-th birthday Abstract. This paper is a historical overview of the development of the topic now commonly known as Laplacian Growth, from the original Hele-Shaw experiment to the modern treatment based on integrable systems. Mathematics Subject Classification (2000). Primary 76D7, 01A70; Secondary 30C35, 37K20. Keywords. Hele-Shaw, Polubarinova-Kochina, Kufarev, Richardson, Taylor, Saffman, Conformal Mapping, Integrable Systems. 1. Introduction One of the most influential works in fluid dynamics at the end of the 19-th century was a series of papers written by Henry Selby Hele-Shaw (1854–1941). There Hele- Shaw first described his famous cell that became a subject of deep investigation only more than 50 years later. A Hele-Shaw cell is a device for investigating two- dimensional flow of a viscous fluid in a narrow gap between two parallel plates. This cell is the simplest system in which multi-dimensional convection is present. Probably the most important characteristic of flows in such a cell is that when the Reynolds number based on gap width is sufficiently small, the Navier-Stokes equations averaged over the gap reduce to a linear relation for the velocity similar to Darcy’s law and then to a Laplace equation for the fluid pressure. Different driving mechanisms can be considered, such as surface tension or external forces (e.g., suction, injection). Through the similarity in the governing equations, Hele- Shaw flows are particularly useful for visualization of saturated flows in porous media, assuming they are slow enough to be governed by Darcy’slaw.Nowadays, Supported by the grant of the Norwegian Research Council #177355/V30, and by the European Science Foundation Research Networking Programme HCAA. -

The committee’s mission was to place the suddenly unemployed and imperiled academics in institutions outside of Germany. -

These theorems, whose importance remained obscure for decades, eventually acquired a considerable influence on the development of modern theo- retical physics, and their history is related to numerous questions in physics, in me- chanics and in mathematics. -

Mathematicians Going East
MATHEMATICIANS GOING EAST PASHA ZUSMANOVICH ABSTRACT. We survey emigration of mathematicians from Europe, before and during WWII, to Russia. The emigration started at the end of 1920s, the time of “Great Turn”, and accelerated in 1930s, after the introduction in Germany of the “non-Aryan laws”. Not everyone who wanted to emigrate managed to do so, and most of those who did, spent a relatively short time in Russia, being murdered, deported, or fleeing the Russian regime. After 1937, the year of “Great Purge”, only handful of emigrant mathematicians remained, and even less managed to leave a trace in the scientific milieu of their new country of residence. The last batch of emigrants came with the beginning of WWII, when people were fleeing eastwards the advancing German army. INTRODUCTION A lot is written about emigration of scientists, and mathematicians in particular, from Germany and other European countries between the two world wars. First and foremost, one should mention a de- tailed study [Sie2], concentrating mainly on emigration to US, but also briefly covering emigration to other countries; then there are a lot of papers concentrating on emigration to specific countries: [Bers], [Rein] (US), [Fl], [NK] (UK), [Ri] (both US and UK), [Sø] (Denmark), and [EI] (Turkey). In absolute figures, the largest number of mathematicians emigrated to US (over 100 by many accounts), while in relative numbers (say, proportional to the size of the population, or to the number of actively working mathematicians in the host country) the first place belongs to UK. Concerning emigration to Russia, besides separate accounts of the fate of individual mathematicians scattered over the literature (a recent interesting contribution being [O]), there is only a very brief survey in [Sie2, pp. -

Classical and Stochastic Löwner–Kufarev Equations Filippo Bracci, Manuel D. Contreras, Santiago Díaz-Madrigal, and Alexander Vasil’ev Abstract In this paper we present a historical and scientific account of the development of the theory of the Löwner–Kufarev classical and stochastic equations spanning the 90-year period from the seminal paper by K. Löwner in 1923 to recent generalizations and stochastic versions and their relations to conformal field theory.

Bracci et al. 1 Introduction The Löwner theory went through several periods of its development. It was born in 1923 in the seminal paper by Löwner [165], its formation was completed in 1965 in the paper by Pommerenke [189] and was finally formulated thoroughly in his monograph [190] unifying Löwner’s ideas of semigroups and evolution equations and Kufarev’s contribution [144, 146]ofthet-parameter differentiability (in the Carathéodory kernel) of a family of conformal maps of simply connected domains ˝.t/ onto the canonical domain D, the unit disk in particular, and of PDE for subordination Löwner chains of general type.
