In this paper, we investigate three problems concerning the toric ideal associated to a matroid. Firstly, we list all matroids M such that its corresponding toric ideal IM is a complete intersection. Secondly, we handle the problem of detecting minors of a matroidM from a minimal set of binomial generators of IM. In particular, given a minimal set of binomial generators of IM we provide a neces...

Guaranteed Annuity Options (GAOs) are options available to holders of certain pension policies. Under these contracts, policyholders contribute premiums into a fund managed by the insurer. At retirement, the policyholders buy life annuities at a guaranteed rate provided by the original insurer, or annuitize with another insurer. If the guaranteed annuity rates are better than the prevailing rat...

In this paper we study different algorithms for reflected backward stochastic differential equations (BSDE in short) with two continuous barriers based on binomial tree framework. We introduce numerical algorithms by penalization method and reflected method respectively. In the end simulation results are also presented.

Due to the recently changing climate and impacts from severe events (smoke taint, heatwaves, droughts, frost, hail floods) there is an urgent need for effective tools tackle multiple risks ensure higher levels of resilience. The Climate Change Adaptation Framework (CCAF), comprises a 5-stage process help make climate-smart choices when considering competing adaptation options grape wine product...

In HTS, the HTK HMM definition (please see HTKBook [1] Chapter 7) has been modified to support MSD [2], stream-level tying, and adaptation of multi-stream HMMs. This section gives its brief description. First, is added to global options of the HTK HMM definition language The arguments to the option are the number of streams (default 1) and then for each stream, 0 (non-MSD st...

The naval domain is characterized by a dynamic environment. This requires constant adaptation of the organization, choosing between a wide variety of options. The consequences of the different options are difficult to foresee and hence, it is hard to judge which option is best. This paper presents automated support for the simulation, visualization, and validation of such adaptive multi-agent o...

The real estate derivatives market allows participants to manage risk and return from exposure to property, without buying or selling directly the underlying asset. Such market is growing very fast hence the need to rely on simple yet effective pricing models is very great. In order to take into account the real estate market sensitivity to the interest rate term structure in this paper is pres...

We propose an efficient fault-tolerant routing algorithm for hypercube networks with a very large number of faulty nodes. The algorithm is distributed and local-information-based in the sense that each node in the network knows only its neighbors’ status and no global information of the network is required by the algorithm. For any two given nonfaulty nodes in a hypercube network that may conta...

We reconsider the valuation of barrier options by means of binomial trees from a “forward looking” prospective rather than the more conventional “backward induction” one used by standard approaches. This reformulation allows us to write closed-form expressions for the value of European and American put barrier-options on a non-dividend-paying stock.
