QUASIMAP COUNTS AND BETHE EIGENFUNCTIONS
Moscow Mathematical Journal. 2017. Vol. 17. No. 4. P. 565–600.
Okounkov A., Aganagic M.
We associate an explicit equivalent descendent insertion to any relative insertion in quantum K-theory of Nakajima varieties.
This also serves as an explicit formula for off-shell Bethe eigenfunctions for general quantum loop algebras associated to quivers and gives the general integral solution to the corresponding quantum Knizhnik Zamolodchikov and dynamical q-difference equations.
Publication based on the results of:
Zabrodin A., Zotov A., Journal of Physics A: Mathematical and Theoretical 2017 Vol. 50 No. 20 P. 1–12
We discuss the correspondence between the Knizhnik–Zamolodchikov equations associated with GL(N) and the n-particle quantum Calogero model in the case when n is not necessarily equal to N. This can be viewed as a natural 'quantization' of the quantum-classical correspondence between quantum Gaudin and classical Calogero models. ...

Institutional development tends to converge to several equilibriums differentiating by the level of development. Institutions external to a country, can help this country to find a “right” equilibrium. CEECs countries on average have institutional performance and economic development below the EU15 average. By choosing the Acquis Communautaire as external anchor CEECs may further improve their ...

The parameters of unstable short-living isotopes are studied from
the mathematical point of view. The values of the chemical potential
and activity parameters that determine the neutron halo arising when
the neutron separates from the nucleus of an unstable isotope are
calculated. The analogy between nuclear physics and economics is
considered from the point of view of such parameters as ...

Urban greenery such as trees can effectively reduce air pollution in a natural and eco-friendly way. However, how to spatially locate and arrange greenery in an optimal way remains as a challenging task. We developed an agent-based model of air pollution dynamics to support the optimal allocation and configuration of tree clusters in a city. The Pareto ...

The paper investigates possible ways to take into account risks, caused by uncertain factors, using the problem of optimal deposit diversification as an applied example. It is assumed that the investor (Decision Maker - DM) does not know future exchange rates at the end of the deposit period, and focuses only on some limits of ...

A meromorphic differential on a Riemann surface is said to be real-normalized if all its periods are real. Real-normalized differentials on Riemann surfaces of given genus with prescribed orders of their poles form real orbifolds whose topology is closely related to that of moduli spaces of Riemann surfaces with marked points. Our goal is to ...

We study set-valued mappings of bounded variation of one real variable. First we prove the existence of an extension of a metric space valued mapping from a subset of the reals to the whole set of reals with preservation of properties of the initial mapping: total variation, Lipschitz constant or absolute continuity. Then we show ...

In this note, we consider a single machine scheduling problem with generalized total tardiness objective function.
A pseudo-polynomial time solution algorithm is proposed for a special case of this problem. Moreover, we present a new
graphical algorithm for another special case, which corresponds to the classical problem of minimizing the weighted number
of tardy jobs on a single ...

Sequential state discrimination is a strategy for quantum state discrimination of a sender’s quantum
states when N receivers are separately located. In this report, we propose optical designs that can
perform sequential state discrimination of two coherent states. For this purpose, we consider not
only binary phase-shifting-key (BPSK) signals but also general coherent states, with arbitrary prior
probabilities. Since ...

Given an action of an affine algebraic group with only trivial characters on a factorial variety, we ask for categorical quotients. We characterize existence in the category of algebraic varieties. Moreover, allowing constructible sets as quotients, we obtain a more general existence result which, for example, settles the case of a finitely generated algebra of ...

В предлагаемом пособии содержатся задачи различного уровня сложности. Однако основной акцент сделан на задачах средней сложности. Это сделано намеренно с тем, чтобы побудить студентов к самостоятельному решению задач: слишком простые задачи решать скучно; слишком сложные демотивируют средних и слабых студентов, а у сильных студентов зачастую отнимают неоправданно большое количество времени, которым в реальном учебном процессе они не обладают.
