Recursive Formula for E(∏i Tr{(WΣ-1)mi}), where W~Wp(∑; n) in finite and asymptotic regime
2015Co-Authors: Jolanta Maria Pielaszkiewicz, Dietrich Von Rosen, Martin SingullAbstract:In this paper, we give a general Recursive Formula for E(∏i Tr{(WΣ-1)mi}), where W~Wp(∑; n) denotes a real Wishart matrix. Formulas for xed n; p are presented as well as asymptotic versions when n/ ...

Welschinger invariants of small non-toric Del Pezzo surfaces
Journal of the European Mathematical Society, 2013Co-Authors: Ilia Itenberg, Viatcheslav Kharlamov, Eugenii ShustinAbstract:We give a Recursive Formula for purely real Welschinger invariants of the following real Del Pezzo surfaces: the projective plane blown up at q real and s ≤ 1 pairs of conjugate imaginary points, where q + 2s ≤ 5, and the real quadric blown up at s ≤ 1 pairs of conjugate imaginary points and having non-empty real part. The Formula is similar to Vakil's Recursive Formula [22] for Gromov–Witten invariants of these surfaces and generalizes our Recursive Formula [12] for purely real Welschinger invariants of real toric Del Pezzo surfaces. As a consequence, we prove the positiv-ity of the Welschinger invariants under consideration and their logarithmic asymptotic equivalence to genus zero Gromov–Witten invariants.

A Caporaso-Harris type Formula for Welschinger invariants of real toric Del Pezzo surfaces
2006Co-Authors: Ilia Itenberg, Viatcheslav Kharlamov, Eugenii ShustinAbstract:We define a series of relative tropical Welschinger-type invariants of real toric surfaces. In the Del Pezzo case, these invariants can be seen as real tropical analogs of relative Gromov-Witten invariants, and are subject to a Recursive Formula. As application we obtain new Formulas for Welschinger invariants of real toric Del Pezzo surfaces.

A Recursive Formula for convolutions/correlations and its application in pattern recognition
Pattern Recognition Letters, 1998Co-Authors: Y. B. KarasikAbstract:Abstract A Recursive Formula expressing N -dimensional convolutions/correlations via ( N −1)-dimensional ones is proposed. Its applications in pattern recognition (especially in optical pattern recognition) are discussed.
