FRACTIONAL SUPERSYMMETRY [PDF]
Modern Physics Letters A, 1995 A symmetry between bosonic coordinates and some Grassmannian-type coordinates is presented. Commuting two of these Grassmannian-type variables results in an arbitrary phase factor (not just a minus sign). This symmetry is also realized at the level of the field theory.

The fractional and mixed-fractional CEV model [PDF]
Journal of Computational and Applied Mathematics, 2020 The continuous observation of the financial markets has identified some stylized facts which challenge the conventional assumptions, promoting the born of new approaches. On the one hand, the long-range dependence has been faced replacing the traditional Gauss-Wiener process (Brownian motion), characterized by stationary independent increments, by a ...

Positivity of fractional descriptor linear continuous-time systems [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2019 The positivity of fractional descriptor linear continuous-time systems is investigated. The solution to the state equation of the systems is derived. Necessary and sufficient conditions for the positivity of fractional descriptor linear continuous-time ...

Fractional hypergraph isomorphism and fractional invariants
CoRR, 2020 Fractional graph isomorphism is the linear relaxation of an integer programming formulation of graph isomorphism. It preserves some invariants of graphs, like degree sequences and equitable partitions, but it does not preserve others like connectivity, clique and independence numbers, chromatic number, vertex and edge cover numbers, matching number ...

Proceedings of the National Academy of Sciences, 2019 An approach to the coalescent, the fractional coalescent ( f -coalescent), is introduced. The derivation is based on the discrete-time Cannings population model in which the variance of the number of ...

Inequality and Fractionalization [PDF]
SSRN Electronic Journal, 2010 We present evidence that ethnic fragmentation explains variations in per capita income, institutions, and schooling better than income inequality when both are treated as endogenous. To do so, we identify instruments for ethnic fractionalization and income inequality based on historical experience.

Fractional variational problems depending on indefinite integrals
, 2012 We obtain necessary optimality conditions for variational problems with a Lagrangian depending on a Caputo fractional derivative, a fractional and an indefinite integral.

Variable Doppler Starting Point Keystone Transform for Radar Maneuvering Target Detection
Remote SensingThe Doppler band compensated by the keystone transform (KT) is limited. Therefore, it needs to be used in conjunction with the Doppler ambiguity compensation function to correct the range migration (RM) caused by maneuvering targets with Doppler ...

Fractional calculus of periodic distributions
, 2011 Two approaches for defining fractional derivatives of periodic distributions are presented. The first is a distributional version of the Weyl fractional derivative in which a derivative of arbitrary order of a periodic distribution is defined via Fourier
