On the Zeros of a Certain Wronskian
Bulletin of the London Mathematical Society, 1988The proof of the Nevanlinna second main theorem for small functions, see [\textit{N. Steinmetz}, J. Reine Angew. Math. 368, 134-141 (1986; Zbl 0598.30045)], is based essentially on the estimate \[ m(r,L(f)^{-1})\leq m(r,L(f))+(2+\epsilon)N(r,f)+S(r,f), \] where L(f) is the quotient of two Wronskian, \[ L(f)=W(y_ 1,...,y_ q,f)/W(y_ 1,...,y_ q), \] with ...

We develop a perturbation method that generalizes an approach proposed recently to treat velocity-dependent quantum-mechanical models. In order to test the present approach we apply it to some simple trivial and nontrivial examples.

Moscow University Mathematics Bulletin, 2011
An associative multilinear polynomial depending on 16 variables and being skew-symmetric with respect to 12 of them is presented. This polynomial provides us with a mapping recovering the algebra of regular functions of an irreducible affine variety from any smooth involutive distribution of dimension 2.

In this paper, the Wronskian technique is applied to the vector nonlinear Schrödinger equation with arbitrary m components, which arises from some applications in the multimode fibers, photorefractive materials, and Bose–Einstein condensates. Via the iterative algorithm based on the Darboux transformation, the (m+1)-component Wronskian solution is ...

Turánians and Wronskians for the Zeros of Bessel Functions
SIAM Journal on Mathematical Analysis, 1980Paul Turan [On the zeros of the polynomials of Legendre, Casopis pro Peěstovani Mat. a Fys., 75 (1950), pp. 113–122] proved that the Legendre polynomials satisfy the inequality $P_n (x)P_{n + 2} (x) - [P_{n + 1} (x)]^2 < 0, - 1 < x < 1$. Here it is shown that the positive zeros of arbitrary real Bessel functions satisfy sjmilar inequalities, even in a ...
