We apply a probabilistic approach developed in our previous papers, which allows us to solve the Cauchy problem for nonlinear
parabolic equations and systems and to construct solutions of problems arising in financial mathematics in search for arbitrage-free
option prices on nonideal markets. Bibliography: 11 titles. 相似文献

DSC studies of melting process of annealed native structures and postdenatured ones in low-amylose starches with different
degrees of hydration were carried out. The starch recrystallization at different thermal treatments of the samples was studied
both after the complete and partial destroy of native structures. It has been shown that native structures as well as postdenatured
ones possess the ability to perfection, which is most clearly seen at the annealing at temperatures inside their melting ranges.
The results obtained demonstrate that at the same duration of annealing the process of crystal perfection for secondary starch
structures proceed more intensively compared to the native ones. The presence of the remained native structures in partial
melt in contrast to the remained gel ones restricts the ability of the recrystallized structures to perfection. 相似文献

We show in this paper that stochastic processes associated with nonlinear parabolic equations and systems allow one to construct
a probabilistic representation of a generalized solution to the Cauchy problem. We also show that in some cases the derived
representation can be used to construct a solution to the Cauchy problem for a hyperbolic system via the vanishing viscosity
method. Bibliography: 12 titles.

In this paper, we show that some well-known equations of mathematical physics can be naturally treated from the probability viewpoint as equations for logarithmic derivatives of smooth diffusion measures. We discuss a probabilistic interpretation of the Darboux transformation applied in the theory of the SturmLiouville equations. It is shown that this transformation can be applied in deriving an explicit expression for the RadonNikodym derivative of a pair of absolutely continuous measures generated by various scalar multiplicative functionals of diffusion processes.

By method of differential scanning calorimetry the absolute values of heat capacity for the systemwater–biopolymer (globular
and fibrillar proteins and DNA) were measured in a wide range of temperatures (from -30 up to 130°C) and concentrations of
proteins both in native and denatured states. Thermal properties of humid denatured biopolymers demonstrate a characteristic
anomaly in the form of the heat capacity jump at temperature depending on the bound water content. It has been shown that
in the systems studied a glass transition, where water serves as a native plasticizer, is observed. It has been established
that the S-shaped character of all heat capacity curves obtained on dehydration for native and denatured biopolymers is due
to the gradual transition to the glassy state of both native and denatured samples. It was found that thermally denatured
humid small globular proteins at subsequent dissolving in water at room temperature are able to restore their native structure.

We construct a Markov process and its multiplicative operator functional associated with a system of nonlinear partial integral-differential
equations (PIDE). As a result we derive a probabilistic representation of the solution to the Cauchy problem for a system
of nonlinear PIDEs in Q
