On the exit of the Gakhov set along the family of Avkhadiev's classes

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2017
Professor F.G. Avkhadiev has played a crucial role in the formation of the finite-valence theory for the classes of holomorphic functions with bounded distortion.

An extension of Hewitt's inversion formula and its application to fluctuation theory [PDF]

open access: yes, 2015
We analyze fluctuations of random walks with generally distributed increments. Integral representations for key performance measures are obtained by extending an inversion theorem of Hewitt [11] for Laplace-Stieltjes transforms. Another important part of

Tiny a priori knowledge solves the interior problem in computed tomography [PDF]

open access: yes, 2008
Based on the concept of differentiated backprojection (DBP) (Noo et al 2004 Phys. Med. Biol. 49 3903, Pan et al 2005 Med. Phys. 32 673, Defrise et al 2006 Inverse Problems 22 1037), this paper shows that the solution to the interior problem in computed ...

Large-N limit of the generalized 2-dimensional Yang-Mills theories [PDF]

open access: yes, 1998
Using the standard saddle-point method, we find an explicit relation for the large-N limit of the free energy of an arbitrary generalized 2D Yang-Mills theory in the weak ($AA_c$) region, we investigate carefully the specific fourth Casimir theory, and ...

On The Douglas-Kazakov Phase Transition [PDF]

open access: yes, 2015
We give a rigorous proof of the fact that a phase transition discovered by Douglas and Kazakov in 1993 in the context of two-dimensional gauge theories occurs. This phase transition can be formulated in terms of the Brownian bridge on the unitary group U(

On the Gakhov Equation for the Biernacki Operator [PDF]

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2015
The paper establishes the region in the parameter plane such that the image of any starlike function with the zero root of the Gakhov equation under the mapping by the Biernacki operator corresponding to the parameter of this region is found in the ...

On the Families of Hyperbolic Derivatives with the Quasi-L ̈owner Dynamics of Pre-Schwarzians [PDF]

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2016
The dynamics of the critical point set for the hyperbolic derivatives of the family of holomorphic functions in the unit disk with pre-Schwarzians satisfying the equation of the quasi-L wner type is studied.

Water entry of a flat elastic plate at high horizontal speed [PDF]

open access: yes, 2013
The two-dimensional problem of an elastic-plate impact onto an undisturbed surface of water of infinite depth is analysed. The plate is forced to move with a constant horizontal velocity component which is much larger than the vertical velocity component

On the Gakhov Equation in the Janowski Classes with Additional Parameter [PDF]

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2015
The Janowski class is characterized by a suitable disk in the right half-plane containing values of the functional ζf0 /f for all functions of this class. The set of such classes-disks forms a two-dimensional family ”filling” ∆ triangle.

Nuttall's theorem with analytic weights on algebraic S-contours [PDF]

open access: yes, 2014
Given a function $f$ holomorphic at infinity, the $n$-th diagonal Pad\'e approximant to $f$, denoted by $[n/n]_f$, is a rational function of type $(n,n)$ that has the highest order of contact with $f$ at infinity. Nuttall's theorem provides an asymptotic
